He has twice been named Sexiest Man Alive by America’s People magazine.

But yesterday, Brad Pitt looked more wolf-man than a Hollywood heartthrob as he left Sony Studios in Los Angeles.

The star sported a greying overgrown beard with his hair looking scruffy and unkempt under a cream trilby hat.

In stark contrast to his glamorous girlfriend Angelina Jolie, who turned 35 last week, Pitt looked every inch his 46-years with his baggy beige style trousers and matching granddad-style jacket.

Perhaps the actor is worn out from looking after his six children; Maddox, eight, Pax, six, Zahara, five, Shiloh, four, and twins Vivienne and Knox, 22 months.

He has been on dad duty while Jolie has been busy filming two movies – action thriller Salt and drama The Tourist alongside Johnny Depp.

Jolie is also said to be in talks to play the renowned beauty Cleoptra in a brand new film adaptation. Film producer Scott Rudin told newspaper USA Today that the project ‘is being developed for and with Jolie.’

Meanwhile, Pitt hasn’t been seen on the big screen since playing a Nazi scalper in Quentin Tarantino hit Inglorious Basterds last year.

He will next be seen starring alongside Sean Penn in fantasy drama Tree of Life, slated for release this autumn.

Let’s hope he recovers his movie star looks by then.
