We finally have some proof regarding Demi Lovato & Wilmer Valderrama’s relationship!  The hush-hush couple was photographed kissing in a passionate embrace this afternoon.

Lovato and Valderrama dated briefly after Demi broke up with Joe Jonas in 2010, but before she entered treatment last fall.  The couple has been linked since then, but have continuously denied the relationship rumors.

Looks like they can’t hide anymore!  Do you think Demi & Wilmer are a serious couple!?  Or is this just a fling?
