London, Jan 30 (Agencies): In line with Demi Moore and Britney Spears, Alicia Silverstone hit headlines as being the next Hollywood star to become a pregnant cover girl.

After the news of her pregnancy came out last week, the 34-year-old showed off her increasing baby bump for the high-end fashion magazine Vogue during a photoshoot, sources said.

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 radient in a long flowing purple gown.
