Wilmer Valderrama kisses Demi Lovato in rare photo

LOS ANGELES, Nov. 18 (UPI) -- Demi Lovato shared a rare photo of herself with boyfriend Wilmer Valderrama on Monday.

The 22-year-old singer posted a black and white snapshot of the 34-year-old actor kissing her on the cheek. Both stars are dressed casually, and Lovato smiles as she receives the smooch.

"I never post personal pictures like this but [expletive]," she captioned the picture. "He is perfect. I miss my @wilmvervalderrama."

Lovato and Valderrama have been dating on and off since 2010. The couple keep their relationship tightly under wraps, although a source did assert the pair are still together in August.

Lovato released her fourth studio album, Demi, in May 2013. Valderrama is best known for portraying Fez on Fox sitcom That '70s Show, and currently stars as Carlos Madrigal on El Rey series From Dusk Till Dawn.
