Hollywood actress Brooke Shields was forced to publicly announce her pregnancy, after her two-year-old daughter ROWAN shared the news with everybody at her playgroup.

Shields, who is preparing for the birth of her second child next year (06), learned of her daughter's disclosure when she read a progress report.

She says, "(Rowan) decided to announce (the pregnancy) to her playgroup. It's the first place I've ever left her alone for a few hours.

"You drop them off and it's just the kids and then you get a little report on the email as to who did what and everything. (The report said) 'Rowan decided to announce to the entire group, "There's a baby in Mommy's belly!"'

"It was before (the news) had broken."
