Demi Lovato and Wilmer Valderrama Dine at Mastro’s in LA Leads Today’s Star Sightings

Why so glum?

While Demi Lovato and boyfriend Wilmer Valderrama were in the mood for some steak, they were NOT in the mood for photos after enjoying a dinner date at Mastro’s Steakhouse in Beverly Hills.

Earlier in the night, Lovato joined country singer Brad Paisley on stage for a live performance on Jimmy Kimmel Live.

Paisley knew how much Lovato loves her dog, Batman, so he painted a photo of the little guy with the superhero Batman.
