London, Feb 13 : Supermodel Kate Moss is tight-lipped over rumours that she is expecting her first child with rocker beau Jamie Hince.

The catwalk queen was recently spotted with a suspiciously swollen stomach as she left The Ivy restaurant in London after a night out with a friend.

She tried to pull her leopard print jacket over the bump, sparking rumours she is pregnant, reports the Daily Star.

And the model has fuelled the rumours by refusing to issue a denial of the reports, or even to comment directly.

A rep for Moss said: "I am afraid it is a private matter" - and declined to comment further.

Moss, who lives in North London, has a six-year-old daughter, Lila Grace, by magazine publisher Jefferson Hack.

She has dated Hince since splitting from rocker Pete Doherty in 2007. (ANI)
