Hands up who knew that Demi Lovato was in a relationship?!

According to contactmusic.com, Demi has been dating Lindsey Lohan's ex Wilmer Valderrama since January, but the two have recently parted ways. Whoa!

A source revealed to the New York Post that the relationship ended because; "the age difference (13 years) meant they were in completely different places in their lives."

Strongs Demi!
