Jennifer Aniston dazzles at premiere

Jennifer Aniston wows at premiere, but is she back with John Mayer?

Jennifer Aniston made a scene-stealing turn at the premiere of new flick, Love Happens, last night, in a dazzling metallic minidress.

Showing off her picture-perfect pins, the actress slipped into the shimmering silver stunner, which she paired with glittering sandals, and left that famous glossy mane loose and long.

But while all eyes might have been on the Friends star's chic style, the Hollywood rumour-mill is back in overdrive, claiming that Aniston is back with ex, John Mayer.

US magazine Life & Style reports that the former couple are secretly dating again. A source claimed: 'Jen's trying to get their relationship back on its feet, so this was a big step. He has a bad reputation with women, but Jen sees John as a sensitive guy who's pretty much had the key to her heart since they first met.'

But there was no sign of Mayer on the red carpet last night, with Aniston cosying up to co-star Aaron Eckhart for her close-up.

The film sees Eckhart play a widower, who attempts to start dating again. And while the film might sound like typical rom-com fare, Aniston was quick to claim it's darker than might be expected, calling the flick less 'light and fluffy' than her typical roles.
