Pregnant Alicia Silverstone poses for 'Vogue'

Following in the footsteps of Demi Moore and Britney Spears, Alicia Silverstone is the next Hollywood star to become a pregnant cover girl.

After announcing her pregnancy last week, the 34-year-old showed off her burgeoning baby bump for the high-end fashion magazine Vogue during a photoshoot, reports Dailymail.co.uk.

The shoot took place at an animal sanctuary, a charity of which she has been a big supporter.

But unlike Spears and Moore, she did not pose nude.

During the shoot, Silverstone laid on a pig, hung out with some cows and sat in a barn with a bunch of turkeys, chickens and ducks, looking radiant in a long flowing purple gown.
