Wilmer Valderrama and Demi Lovato 'On Again'

By Simone Hilliard

Just four weeks after her three-month rehab stint for "emotional and physical issues," Demi Lovato appears to be following in the foot steps of that other Disney starlet-turned-rehabber. The Camp Rock star is reportedly dating 31-year-old Wilmer Valderrama, whose celebrity exes include Jennifer Love Hewitt, Mandy Moore, Avril Lavigne and, yes, Lindsay Lohan.

The pair reportedly started dating last May, after Lovato's very public split with Joe Jonas, and have resumed their "friendship" in the last few weeks. Attempting to keep a low profile, the two have been spotted at a Whole Foods in Tarzana and, more recently, at the Sherman Oaks Galleria this weekend, according to Perez Hilton.

While the two do make an undeniably cute couple, we're not sure we get the attraction. Wilmer, who is 13 years Demi's senior, can likely provide her with some much-needed guidance and stability. But what can Demi possibly offer Wilmer?

Perhaps a career revival. The That '70s Show actor hasn't been seen much since his MTV show, Yo Momma, ended its run in 2007. Valderrama also famously dated an 18-year-old Lindsay during the height of her celebrity, after the 2004 box office hit Mean Girls, and just as his 70s Show gig was slowing down. Of course, Lindsay didn't go to rehab until three years later, in 2007, but her career began to spiral on the set of Herbie: Fully Loaded, when some attributed her negative attitude and tardiness to her break-up with Wilmer.

Could the same fate hold true for Demi? As she strives to return to a regular routine, a new relationship could hinder her progress or provoke rehab part deux for the singer. Unless, of course, their burgeoning love led to the back-up dancer beatdown that sent her to rehab in the first place. We may never know, but judging by the length of most Hollywood romances, we just hope Demi keeps herself together when it's all over.

What do you think: Is this true love or a business deal for Wilmer? Sound off in the comments or @MTV3.
