Jessica Alba has already turned down three offers to show off her baby bump in revealing magazine photoshoots.

The Fantastic Four actress – who announced last week that she is expecting a late Spring baby with on/off boyfriend, Cash Warren- has decided not to follow the likes of Demi Moore and Christina Aguilera by baring all for the glossies.

A friend says: "She had three offers on the first day, but she doesn't intend to take any of them."

Meanwhile, a gaffe by Jess’s Fantastic Four co-star Doug Jones has sparked rumours that she and cash have become secretly engaged.

Speaking at the Jules Verne Adventure Film Festival at the weekend, the actor referred to Cash as her fiance.

He said: "Jessica and her fiance are wonderful, and they're going to make the most beautiful babies ever."
