Jessica Alba has given friends leather bracelets and told them not to take them off until after she gives birth.

The 'Fantastic Four' actress, who is expecting her first child with fiance Cash Warren in May, had a baby shower in Los Angeles at the Ever After Tea Shop, where guests including Kim Kardashian and Rashida Jones were asked to take part in the bizarre ritual.

Mom-to-be Jessica Alba celebrated the upcoming birth of her baby at a shower Sunday with 40 guests. The actress celebrated with her girlfriends, although fiancé Cash Warren arrived after the luncheon to help take away the gifts.

The lunchtime baby shower was held at Ever After Tea House in Studio City. During the shower Alba announced that she is expecting a girl.

Nicole Richie and Joel Madden have started a children's library for their unborn baby.

'The Simple Life' star - who is due to give birth to her first child in January - and the Good Charlotte frontman gave all their baby shower gifts to charity, but kept a book from each guest.
