Pink is reportedly pregnant with her second child.

The 34-year-old singer, who already has two-year-old daughter Willow, has sparked rumours she's expecting another baby with her husband Carey Hart after her beau was seen rubbing her stomach in New York last month.

A source told OK! USA magazine: ''They were cuddling and he kept rubbing her tummy. She was quick to move his hand away in case anyone saw. But it was pretty obvious.''

The pregnancy rumours don't come as a complete surprise as the 'So What' hitmaker - whose real name is Alecia Hart - admitted last year she is desperate to extend her family because she thinks motherhood is the ''best thing''.

She said at the time: ''I want a basketball team [of kids]. It's [motherhood is] the best thing I've done.

''In 10 years I'll have an 11 year old and an eight year old and a five year old and a three year old and a six month old and 18 dogs, a horse and a pig.''

Pink and Carey began dating in 2001, before getting engaged in 2005 after the blonde beauty proposed to the hunk during a motocross race in California.

The couple got married a year later in Costa Rica on January 7, 2006.
