Blooming Jessica Alba gets ready for baby

Jessica Alba put her baby bump on show during a shopping trip in LA yesterday, trading in her glamorous Oscars look for street chic.

Jessica, who recently revealed she is in her "third trimester", opted for a relaxed approach to fashion after making a dazzling appearance at the Academy Awards earlier this week in a strapless Markesa dress with Cartier jewellery.

She presented a gong at the ceremony, and noted on her MySpace blog she was relieved to have made it through without tripping over her dress on stage.

But she did lose her balance away from prying cameras.
