Casper Smart continues to be the luckiest man in America. He has sex with Jennifer Lopez, travels the world, and gets paid for busting a nut on a regular basis. Where can I sign up? Casper and maneater Jenny were spotted partying in Rio de Janeiro, Brazil over the weekend, celebrating Carnival.

They do everything together, like photo shoots! Just days ago, Jen posted a professional looking photo of herself and Casper on Twitter, and then quickly deleted it.

Jennifer has a very intense schedule: Working on American Idol, having sex with a 24 year-old, raising 2 year-old twins, pissing off her ex, Marc Anthony. Whorin’ ain’t easy!

I hope Jennifer had Casper sign a confidentiality agreement. I can just see him selling her out when this f*ckship explodes within the next few months. Jen is supposed to present at the Oscars this Sunday. I bet Casper will be there walkin’ the red carpet, rubbin’ her a*s thinking about what he’s gonna buy next.
