Kristin Cavallari and Jay Cutler announced that they're expecting their first child less than two months after getting re-engaged. So what's the deal? Was the couple so happy to be back together that they decided to rush right into parenthood? Or was Kristin's pregnancy an unexpected surprise?

According to sources close to Jay and Kristin, the couple were "shocked" by the news and may have reconciled as a result of the pregnancy, not the other way around. That's right - Kristin may have gotten knocked up from an ex sex session and she and Jay decided to reconcile to avoid a scandal. Sounds about right.

Regardless of exactly when Kristin got pregnant, the couple certainly weren't planning on having kids anytime soon. Though they always wanted to start a family, sources say they hoped to be married for a few years first. Whoops!

Someone didn't wanna get dumped again! Kristin Cavallari and Jay Cutler are expecting their first baby! Kristin and her fiance Jay Cutler met in August 2010. Just eight months later, Jay proposed in April and then he dumped Kristin in July.

A source says: "She is really happy. She is in the early stages, but she can't wait to be a mom. They have just bought a house in Tennessee and can't wait to start their family."

Jay and Kristin got back together again last year and they announced that they were engaged again in November. Last month, Kristin said: "The past year has been interesting. There have been a lot of ups and downs, but overall it's been great."

Kristin is a smart girl, pulling the classic golddigger move by getting herself preggers! It's also the only way that she could remain semi-relevant.

I think their baby is gonna be so cute! Congrats to the happy couple!!

Reality TV has been Kristin Cavallari is engaged to Jay Cutler again! Kristin Tweeted: "This time it's official..Jay and I are engaged again."

Life & Style ran a story a week ago saying that Kristin was spotted wearing a 5.2 carat engagement ring on Nov. 29. She was "definitely making a point to show off her engagement ring and couldn't stop smiling."

Jay dumped Kristin like a month, or weeks, before they were scheduled to get married this year. Kristin told Life & Style: “I can’t decide if I want a small intimate affair or a huge one. But, it will be classic and traditional.”

Congrats again.

Kristin Cavallari's Marine Corps Ball date didn't even have to create a YouTube video to ask her out, he simply sent her a Tweet! Kristin attended the Marine Corps Ball on Thursday. She had accepted Lance Cpl. Jonathan Burkett's invitation in August.

Kristin was among 1,600 Marines and their dates at the Temecula, Calif., event, just north of San Diego.

Jonathan told Kristin that he's glad she got to attend the event. Jonathan Tweeted Jay Cutler: "Glad she was able to come! You have an awesome girlfriend and hopefully wife!"

Kristin said that she had a great time at the event with her date! She looked really cute in her dress. Justin Timberlake attended a Marine Corps Ball last Saturday, and Mila Kunis is next! Her scheduled Marine Corps Ball goes down tonight!!

Awwww. If only people knew what a slut Kristin Cavallari is IRL, they wouldn't be surprised about this story! Kourtney Kardashian banned Scott from visiting the DWTS set to watch Rob Kardashian compete because she had learned that he had sex with Kristin. Kourtney and Kristin were close friends for years, and were often photographed hanging out together, yet that didn't stop Kristin from sleeping with Kourtney's man!

Life & Style magazine reports that Kristin and Scott Disick hooked up while Scott and Kourtney were on a break (shortly before she got pregnant with Mason). But the betrayal didn't end there!

"Scott and Kristin were hooking up on and off for a year, maybe even two. When Kourt and Scott would fight, he’d party with Kristin and hook up.”

Sounds about right to me!! Jay Cutler doesn't know what he has comin' if he actually wifes up Kristin.

Kristin Cavallari had done a pretty good job with her routines on 'Dancing with the Stars'. I thought she had a good chance to make it to the finals, but apparently most of America didn't think she has what it takes, and she was eliminated from the show last night.

Everyone seemed shocked when it was announced that Kristin was going home and she admits she's a little shocked too.

"I'm a little surprised to be honest, but I've had such a great time and it's been an awesome experience, so it is what it is."

During her appearance on Jimmy Kimmel Live last night, Kristin admits her 'personal story' dance may not have been touching enough to bring in the votes.

"It's hard to compete with some of the most memorable years -- mine was, 'I graduated from high school'.

She's right. What has she experienced besides 'The Hills'? I think they should get rid of the personal story dance in the future because some people are going to get a sympathy vote even if their dance was sh!teous. Kristin wasn't nearly as uptight or offbeat in her dances as some of the other contestants are. I can't believe she was booted so early in the competition!

You can check out Kristin's performance from this week, after the jump!

Kristin Cavallari and Jay Cutler dated for seven months before getting engaged in April. Only three months later, Jay called off their engagement. Jay's fans were going in on Kristin after the split, and Jay was very upset about it, vehemently defending her. The NFL player's defensiveness meant one of two things, (or in this case both): Jay still had feelings for Kristin and 2) He wanted to tap that again.

People magazine is reporting that Kristin and Jay are an item again.

"They're not officially engaged again but they're definitely talking and figuring things out. They're just taking things slow" and "talking a lot," claims the source.

We saw this one coming. Good luck.

Reality TV has been Kristin Cavallari is rumored to be dating her Dancing With the Stars partner, Mark Ballas. Every season, pairs of contestants are romantically linked because tabloid writers can't seem to resist taking it there.

Jay Cutler dumped his maneater fiance and Mark Ballas and Pia Toscano are no longer secretly dating, so they're both available. Cue rumor!

Mark spoke about Kristin, saying: "She is a sweetheart. We have a lot of fun. We both laugh a lot. We're getting along great."

Kristin Cavallari is a rapidly aging hooker who had a reality TV career about three years ago. Since then she has continued to sleep her way through Hollyweird, getting engaged and dumped by NFL player Jay Cutler.

Dancing With The Stars has always been more like Dancing With the Has Beens Who Desperately Want Work, so ABC has added Kristin to its roster.

Since Kristin filled in for Lauren Conrad on the now canceled "Hills" series, she's been grasping at straws.

Snooki said that she's not a part of the cast, but sources reveal that ABC is still trying to book her.

The official Dancing With the Stars cast will be announced on Aug. 29.
