The Black Eyed Peas star - who was rumored to be expecting her first child with fiance Josh Duhamel after sporting an unusually large tummy when she left a sushi restaurant last week - wants to enjoy being engaged before she thinks about starting a family.

She said: "I've never been pregnant and this is probably the 20th time people have said that. So, no, for the record!"

"All I know is that I want to be married before I get pregnant. You're only a fiance for a short amount of time and you want to enjoy that moment so we're just living in the now and enjoying that."

Fergie - who met Josh when the Black Eyed Peas appeared on his US TV show "Las Vegas" in 2004 - also revealed excess weight is more obvious on her body because she is so short.

She added to US TV show "Extra": "I'm 5ft 4in and so when I gain a few extra pounds, it shows. I think people just love to speculate!"
