Demi Lovato still dating 70′s Show’s Wilmer Valderrama?

[HMG Celebrity News] – Actors tend to seek emotional strength from their peers when their love-life goes sour. Courteney Cox did it with ‘Cougar Town’ co-star, Brian Van Holt. As we mentioned previously, Demi Lovato has been reportedly easing the pain of losing Joe Jonas in the company of ‘That 70′s Show’s Wilmer Valderrama.

The pair have known each other since they filmed a public-service announcement in March, to support earthquake relief in Chile. And that’s about the same time as Demi revealed her connection with Joe.

But prior to entering treatment for what her rep skillfully called ‘emotional and physical issues,’ insiders say the 18-year old introduced 30-year old Wilmer to all her pals as her boyfriend.

“They started seeing each other in May, right after her breakup with Jonas,” a source on the tour told  the Post. “She’d show us pictures of them together.”

Another snitch claims Wilmer’s been a big part of Lovato’s life, right up to the time she decided to seek treatment.

But the man’s background’s disturbing — He dated Mandy Moore for 18 months in 2001, then Lindsay Lohan in 2004. He’s also bragged to Howard Stern about the size of his…er, ‘talent,’ claimed to have been Mandy’s first lover, and given Jennifer Love Hewitt and Ashlee Simpson high marks for performance in bed.

Mr. Jonas, however, has kept a dignified silence — He’s now dating ‘Twilight’ star Ashley Greene and they seem pretty close.

Lovato’s rep had no comment on a possible romance, while Wilmer’s people flat-out denied such a connection. You know — the ‘They’re just friends’ line.

Like we’re supposed to believe that.

But those are the facts, guys — Let’s hear your views on this?…
