Demi Lovato Watches Silva Take on Diaz with Wilmer Valderrama!

Demi Lovato attended the Anderson Silva vs. Nick Diaz UFC Fight in Las Vegas tonight, January 31. Held at the MGM Grand, Demi was joined at the event by her boyfriend, Wilmer Valderrama.

Earlier this week, Demi helped Wilmer celebrate his 35th birthday in Los Angeles. The pair celebrated the day with a bunch of Wilmer’s other friends, including Mila Kunis and Ashton Kutcher, by grabbing dinner and singing karaoke.

I am loving Demi’s lipstick! It looks great on her!
