Demi Lovato reunites with ex Wilmer Valderrama

After reports that X Factor judge Demi Lovato was dating One Directions Niall Horan, new reports now suggest the "Give Your Heart A Break" singer has gotten back together with her ex-boyfriend Wilmer Valderrama.

Entertainment Wise reports that the on-again-off-again couple have been linked together since 2010.

The couple reportedly attended a private West Hollywood party over the weekend, where an onlooker said, Wilmer stayed by Demis side all night. He was very protective of her and had his legs straddled around her chair while they watched the show.

According to E! News, the couple was spotted out last weekend having dinner at El Torito in California.

Wilmer also tweeted his apparent new girl on her birthday writing, Feliz Cumpleanos to my angel @ddlovato, U continue 2 make me proud. U are the hero this generation its been waiting 4! With & by you always.

Despite their previous break-ups, it quite obvious the That 70s Show actor really does care about the darling ex-Disney star.
