Demi Moore has apparently hit it off with a new man – True Blood star Joe Manganiello.

According to reports, Demi Moore, 49, and Joe Manganiello, 35, were spotted enjoying each other’s company at the after-party following the premiere of the actor’s new movie That’s My Boy at Los Angeles’ Napa Valley Grille earlier this month.

A source told heat magazine: “They looked amazing together. Demi was getting a lot more attention than a lot of the younger girls in the room, and Joe was seen waiting for her before they went off and hung out together at the party. They had amazing chemistry.”

The pair first met when they both signed up to appear in the movie Magic Mike, in which Joe Manganiello stars as stripper Big Dick Richie.

And despite Demi Moore pulling out of the film following her breakdown, the pair have reportedly kept in touch.

The source added: “Demi has finally got her groove back – and it’s all thanks to meeting Joe. She’s feeling confident again and, more importantly, sexy.”

However, it remains to be seen what Demi Moore’s ex Ashton Kutcher makes of her new relationship, as he actually starred alongside Joe Manganiello in an episode of sitcom Two And A Half Men last year.

Meanwhile, it has also been claimed that Demi Moore has gained nearly a stone after sticking to a new healthy eating regime.

The actress had sparked concern with her worryingly thin frame when she dropped to less than seven stone ahead of being admitted to rehab.

Now Demi Moore, who was spotted at her daughter Tallulah’s graduation on June 7th, is looking much healthier after adopting a new eating plan.

An insider told heat: “Back then Demi was basically living on Red Bull but now she’s eating balanced meals that include protein, complex carbs and organic vegetables.

“She’s also been swimming and doing yoga every day and has gained just over a stone.”
