Demi Lovato, Wilmer Valderrama Spotted Out Together

The Disney starlet and 'That '70s Show' alum reignite dating rumors.

Rumors are sparking up again that former "That '70s Show" star Wilmer Valderrama, 31, and post-rehab Demi Lovato, 18, are dating. The twosome have most recently been spotted on a movie date in Sherman Oaks Galleria's Arclight Cinemas in Los Angeles, as well as at a Whole Foods, according to Perez Hilton.

Talk of a romance between the two first surfaced before Lovato entered treatment in the fall for "emotional and physical issues." But in November, Wilmer's rep denied the rumor to Celebuzz.

Valderrama has been linked with his fair share of young starlets in the past, including the ineffable Lindsay Lohan. In fact, Wilmer made headlines in 2006 for blabbing to radio host Howard Stern about his array of female encounters, including Ashlee Simpson, Jennifer Love-Hewitt and Mandy Moore.

Whether or not Wilmer's wild ways have subsided is still up for debate, but the tabloids haven't put the Venezuelan actor in a bad light for some while. The actor has even guest-starred on Disney's "Wizards of Waverly Place," where he played the uncle of Lovato's BFF Selena Gomez.

Meanwhile, Lovato, who completed her treatment in late January, is slowly but surely getting back to where she left off, which hopefully means she will return to her Disney show, "Sonny With a Chance," soon. Demi has also said she plans to record new music and get back on the road later this year.
