Demi Lovato and Wilmer Valderrama are doing it again

Demi Lovato shopping in West Hollywood (10/6)

Demi Lovato and Wilmer Valderrama used to date back in the day, and then Demi went off the rails, did too many rails, and ended up in rehab. Wilmer must have realized that sex with crazy chicks can be pretty fun because the two are back together and were spotted getting "hot and heavy" at Seth MacFarlane's party last week. A witness told Life & Style:

"They showed up together and made no effort to hide that they're back together. They were stealing kisses throughout the night, holding hands and just seemed to enjoy being together. Demi couldn't seem happier about it!

"They were dirty-dancing to the music, and when they were seated, Wilmer had his hands on Demi’s knee the entire time. He was being very boyfriend-like and affectionate."

Demi is still dating Wilmer? I guess now we know why she likes to cut herself. In all seriousness though, what do all of these hot starlets see in this guy? Finding a tiny Latin dude to date in Southern California isn't exactly hard to do -- just stand out in front of Home Depot. Besides, as a millionaire in his 30s, Wilmer shouldn't be dating a 19-year-old. That's disgusting. He should be dating someone younger.

are you really serious? "I guess now we know why she likes to cut herself" are you joking? what is wrong with you? do you find that witty or clever? because it isn't. it's cruel

She might have a virgin hole, she is certainly homely enough. She is a one, possibly two bagger.

WTF

I'm pretty sure it's standard Disney contract language that states any remaining virginity (front or back door) will be taken by Disney execs during the interview process.

Wilmer and her have history, there is a rumor that Wilmer was the one who popped Demi's cherry.

If that's true I must say DAMN you Wilmer xD

The only cherry he popped was the anus because we all know that's the only type of fruit Fez picks in his country.
