Kelly Osbourne had a very public meltdown with her ex-fiance on Twitter. Over Christmas weekend, Kelly tweeted: "Luke Worrall is the biggest piece of s**, he has been trying to get back with me... Meanwhile, he has been f***ing hundreds of girls...behind my back.

All he did was use me. All girls, beware of @Luke_worral he is a using C***! He used me for my money and a free ride." And then there's this gem: "He is the worst thing that ever happened to me. I don't give a f*** what happens to him anymore...I am and always will be too good for him..." If you say so!

So I guess it's safe to assume that Kelly's new boyfriend, Rob Damiani, 26, doesn't follow her on Twitter.

Kelly was in England for the holidays and she was reportedly depressed and lying around in bed until her friends made her go clubbing, which is where she met her new man, Rob, who sings in the band Don Broco.

Kelly is such an emotional, psycho co-dependent beeyotch. Kelly's ex may have used her for money, and this dude may be using her to get his band publicity. Still, Rob's pretty cute for a nerdy looking guy.

Kelly Osbourne comes to the defense of Miley Cyrus in the wake of Miley's bong smoking video leak. Kelly and Miley are in New Orleans filming a new movie called So Undercover. Meanwhile, Miley herself doesn't even care about the "scandal."

Kelly said: "Just read in the rags that apparently my mum [Sharon Osbourne] thinks Miley is a bad influence on me. It could not be farther from the truth! Miley has us all on a health kick. Gym/early nights."

And as far as the video goes, Kelly said that Miley made "one mistake, and trust me she has learned her lesson! This really makes me mad. Miley is one of the most hard working respectful women I have ever worked with I am learning a lot from her!"

Kelly also added, "Miley and I have become really close. I'm sick of all the haters judging her."

I don't agree with celebrities like Mila Kunis and Melissa Gilbert saying that Miley Cyrus was smoking marijuana, considering that they weren't at the party themselves, that's lame and they should learn how to refrain from commenting on every question that someone asks them. I also find Kelly's emotional comments to be especially funny, cause I highly doubt that Miles would come to Kelly's defense like this if she were caught up in a similar scandal. Kelly, relax! Miley doesn't care about you; she's only hanging out with you cause she's in a random city and she's bored. 

Wow. Kelly Osbourne has come a looooong way in the past year! She began her weight loss while competing on Dancing with the Stars, and remained committed to being fit afterward and has dropped 50 pounds. With her newfound confidence, Kelly even showed off her sexy new bod while performing with the Pussycat Dolls this year. 

Kelly says she's never worn a bikini in her life and she's glad she put in the effort, and consistently worked hard to get in shape.

"Ultimately, I'm really glad I lost the weight the way I did. I never thought in a million years I'd be that healthy girl who wakes up every morning to exercise. After being called 'cherubic and chubby,' I'm rocking a bikini! I feel silly, but I think I'm going to cry. Being on the cover of SHAPE is the biggest victory I could ever hope for."

Just because you struggle with weight when you're growing up, doesn't mean you were born to be fat. You gotta be dedicated and motivated not only to lose the weight, but to keep it off. You may be chubby now, but that doesn't mean you can't be fierce in a bikini like Kelly O. Way to go, girl!

Holy hotness! Kelly Osbourne is looking fabulously fierce wearing nothing but panties and gold paint in a remake of a classic scene from the James Bond movie Goldfinger. Kelly, who turned 26 yesterday, was persuaded to strip and don the gold paint to mark the launch of Sky+HD reaching over 50 channels in High Def.

I love watching TV in HD, you really can see everything in a lot more detail and it makes everything look so much better. Although if you’re on the other side of the camera then the pressure is on you to make sure you look good!

'Since my weight loss I’m a lot more body confident in front of the camera. It’s not just celebration for Sky+HD, but for me too.'

Wow. It's amazing what a transformation Kelly Osbourne has made over the last couple of years. We watched her grow up in front of our eyes and we've seen her slim down. Kelly's big weight loss came when she was a contestant on Dancing with the Stars, but she has worked hard to keep the weight off and she's looking good!

Kelly performed with the Pussycat Dolls last night and I'm sure she didn't disappoint. She looks absolutely amazing in these cute little outfits, and I'm sure being truly comfortable in her own skin gave her the confidence she needed to perform in those skimpy get-ups.

Check out more photos of Kelly's hot little outfits and PCD performance after the jump!

Kelly Osbourne has battled with weight issues for years, but after competing on Dancing with the Stars along with working out and dieting, she has lost 40 pounds. She looks amazing!

In an interview with People, Kelly says she is much more confident with her body now and she's very happy with the way she looks. When she was heavier it hurt her chances of getting clothing from designers but that has totally changed.

"Before, PR companies were horrible and didn't want to give me clothes and didn't want me to wear their clothes. This year every single morning when I wake up to a bellman at my door with a rack of clothes for me to pick and I'm like, 'Oh my God!' "

Kelly is doing a low Glycemic Index diet that cuts out sugar and carbohydrates and she's also doing "the bar method between Pilates and ballet. It's incredible to start getting muscles in places on my body that I never knew I could get."

Work it girl! It's awesome she's lost weight, but it kinda sucks that designers don't want chicks with a little extra thickness wearing their clothing. I understand they want their clothes seen on small beautiful people, but we're not all 5'9 and a size 2!

I can't figure out who looks worse. Paris' wonk, chiseled jaw, and giraffe-like arm are scary while Kelly Osbourne looks like a dirty, smelly patriotic lezzie clown.

Kelly Osbourne needs to remain in rehab. That is not the face of a sober woman. Her ridiculous tattoos and her ensemble makes me wanna spread her out in the wilderness somewhere and leave her there until birds poop on her.

I was just saying a couple weeks ago that Kelly Osbourne was looking good. Ever since then it seems like everything has gone down hill. She was recently arrested for slapping a bitch. Now Sharon Osbourne has confirmed to Radar Online that Kelly is back in rehab.

"Yeah, Kelly's in rehab. What else can we say? She knew that it was the right thing to do at this point and we're proud that she did it. The family is all standing behind her. Kelly knew that she needed help and she's getting it."

Sharon didn't want to reveal the location of the rehab facility where Kelly will be for at at least the next 30 days, except to say that it was outside the L.A. area. Nor did she want to discuss what she's getting help for. "Kelly will tell you herself when she gets out," Sharon promised. "We just pray that everything's going to be okay."

Sharon said that Kelly had been working steadily with her, dad Ozzy Osbourne and brother Jack on Fox TV's new Osbournes Relodaded variety show prior to her entering rehab. "She been working right up until she went in."

Her voice choking with emotion, Sharon ended by saying, "This is one of the absolute worst things that a parent can face, for their child to go through rehab. And not once, but twice. "However, we are all very glad Kelly's doing it."

It's so disappointing, but it's good that she's getting help. Kelly struggled with a painkiller addiction back in 2004 when she checked in to rehab. A little over a year after that Kelly checked into another drug treatment center  after she relapsed. We can only speculate that this is the case again.

Kelly Osbourne was arrested for putting some hater bitch in her place by slapping her after she called Kelly's fiance, model Luke Worrall, "stupid."

Here's a picture of the fug ho Kelly put the slap-down on, Zoe Griffin.

Kelly was at a SoHo club when Zoe insulted her man, prompting the attack.

'She was arrested for common assault relating to an alleged incident in Soho in the early hours of 29 August 2008.' She has been bailed until a date in March."

In an interview with Closer magazine, Kelly said,

'I've never been this mushy with anybody ever before, but this time I can't help it. He's perfect. Everything about him is brilliant. 'I'm happy. I love him and I'd do anything for him.'

Isn't this romantical? You know it's love when you're ready to fuck a ho up when she says some shiz about your dude! I wanna slap that Zoe bitch myself just because she needs to whiten her teeth and cover up her fivehead.

Kelly Osbourne has been looking really good lately. Am I crazy? I think she's gotten over her grungy fugly phase and has moved on to be a lady. She looks great and her shiba inu puppy is adorable.

PS: What are with those crazy Asian girls doing in the background? They must be feeling Kelly like I am.
