There was a time when Isla Fisher was an open book, but that time has passed. Telling the Times Online that she has “more to protect now,” the 32-year-old actress says that “some topics are off-limits.” Among them are her 15-month-old daughter Olive and fiancéSacha Baron Cohen; During the interview, Isla repeatedly checked her Blackberry for updates from a babysitter, but volunteered little about life at home. “It can be tough because motherhood is one of my most favorite things ever,” she explains.

At the opposite end of the spectrum is exercise. The producers of her new film Confessions of a Shopaholic hired a personal trainer to help Isla shed the 60 pounds she gained while pregnant, and they had their work cut out for them! “[They] said I was lucky I was blessed with good genes because I had a really bad attitude towards exercise — like stopping when it hurt or got boring and having a cup of tea and a slice of cake,” she says. “Apparently you are not supposed to do that in Hollywood.” When the cake and tea begin to add up, Isla reaches for Spanx.

Confessions of a Shopaholic is in theaters Feb. 13.
