London, Feb 15 : Supermodel Kate Moss is three-months pregnant and is due to give birth at the end of August, according to sources.

The 35-year-old is expected to formally announce the pregnancy soon, ending weeks of speculation.

According to sources, the catwalk queen has already broken the news to close pals.

Moss and her rocker beau Jamie Hince are said to be thrilled.

Moss, who already has a six-year-old daughter Lila Grace from her relationship with magazine publisher Jefferson Hack, can't wait to be a mum again, say sources.

"He's really excited at the prospect of becoming a dad. He already dotes on Lila Grace and is besotted with Kate.

"She's a devoted, loving mother who enjoys a wonderful relationship with Lila despite a career that takes her all over the world.

"She's vowing to be an even better mum this time," the source added. (ANI)
