Fergie's rep denies pregnancy rumors

Fergie's rep has denied rumors the singer is pregnant with fiance Josh Duhamel's baby.

The 'London Bridge' singer - who recently set tongues wagging at the Grammy Awards when her dress appeared to show a baby bump - is "not preggers," her rep insists.

"It's not true," Duhamel's rep adds to Us Weekly magazine. "She is not pregnant."

Fergie - real name Stacy Ferguson - has been dating Transformers star Duhamel, 35, since September 2004. They got engaged in December.

Fergie, 32, has previously spoken of her desire to settle down and start a family. She said in the past: "It is one of my dreams to have babies with Josh. It will be so special when it happens."
