Charlize Theron slobs out on the beach in a frumpy playsuit

Charlize Theron may be a Hollywood A-lister but when she's not working, the actress likes to slob out just like the rest of us.

The 33-year-old star proved she was just an ordinary girl at heart, when she took her dogs for a walk along the beach in Malibu, California.

Wearing a baggy blue playsuit, cap and flip flops combination, her casual look was a million miles away from her glamorous red carpet image.

Yet despite wearing an outfit which would reduce most mere mortals to shapeless blobs, the Hancock actress still looked radiantly healthy and showed off an enviable pair of pins.

Charlize was accompanied on her stroll by her mother Gerda, who was dressed in a similar casual outfit and flip flops.

The star previously proved that perfect looks were not top of her agenda, when she put on weight to play serial killer Aileen Wuornos in the 2004 film Monster.

At the time of the movie, which won her an Oscar, she spoke out against the culture of beauty in the showbiz industry.

The actress, who was named Esquire's Sexiest Woman Alive in 2007, said: 'Somewhere along the line we forgot what actors do.

'All of a sudden, somehow, the fashion industry crept into the movie industry. Celebrity has really taken over and overshadowed what actors do.

'Actors aren't supposed to be beautiful; actors are supposed to tell human stories, but that kind of got lost.'
