Pregnant Gisele Bundchen is reportedly having a girl.

The 29-year-old Brazilian supermodel - who is expecting her first child with her American football player husband Tom Brady - is said to be thrilled she is having a daughter and has already decided the tot will sleep in the crib she did when she was a baby.

A source told Life and Style magazine: "There's going to be a room off the side of the nursery where the nanny will sleep. And they're using a crib that's been in Gisele's family for four generations. Her grandmother slept in this crib, her mom slept in this crib, Gisele slept in this crib, and now Gisele's daughter will sleep in this crib. It's beautiful solid oak."

Gisele - who is due to give birth in December - had wanted to decorate the nursery pink but has now opted for a nautical theme with green and cream colours.

It had been reported the couple were expecting a boy and had decided to name their infant Gabriel.

New England Patriots player Tom - who already has a two-year-old son, John, with actress Bridget Moynahan - recently spoke of his excitement at becoming a father again, insisting it will be easier than his American football training.

He joked: "It couldn't be harder than this training camp, so I'll be prepared."
