Demi Lovato back with Wilmer Valderrama

Demi Lovato has rekindled her romance with ex-boyfriend Wilmer Valderrama. The 19-year-old singer split from the 31-year-old actor in June, but on Saturday night the pair were spotted kissing at Family Guy creator Seth MacFarlane‘s house party at his Los Angeles home.

“They showed up together and made no effort to hide that they’re back together,” an onlooker said. “They were stealing kisses throughout the night, holding hands and just seemed to enjoy being together.”
 
The pair even indulged in some “dirty dancing” at the party and were virtually inseparable all night.
 
“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,” said the mole.
 
Demi and That 70s Show star Wilmer allegedly decided to split in the summer because the age gap was causing problems in their relationship as they were in “completely different places in their lives”.
 
The Skyscraper singer has endured a difficult past year and she entered rehab in November 2010 for 12 weeks to receive treatment for an eating disorder and self-harming issues and while at the facility Demi was diagnosed with bipolar disorder.
