Demi Lovato and Wilmer Valderrama are rumored to be getting back together!

About two years ago, the couple broke up for the first time, but they've been on-and-off ever since. They tried things out again late last year, and then worked together on a campaign for Vote Latino this summer.

Although rumors have been flying about Demi dating Niall Horan from One Direction, Demi has said it's just a friendship.

A source said to E! News that they're definitely dating, and even celebrated her birthday together. This weekend, they went out to dinner at El Torito.

Demi and Wilmer have definitely been hanging out together. There are photos that prove it - the one above is from their dinner together.  However,  the talk about them being a couple again could just be gossip. We'll have to wait and see...

Wambie girls, do you think it's a good idea for Demi to date Wilmer again?
