Pink has sparked more rumours she is pregnant again.

The 'Just Give Me A Reason' hitmaker, who already has two-year-old daughter Willow with husband Carey Hart, further fuelled speculation she is expecting their second child today (23.05.14), as she appeared to reveal her pregnancy cravings on Twitter.

The 34-year-old star tweeted: ''I love that every time I find a box of Girl Scout cookies I'm pregnant. Guilty: I'm having a thin mint:)''

The singer's mysterious comments come shortly after her husband was spotted rubbing her stomach in New York City last month.

An eyewitness previously said: ''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 '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: ''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 she proposed to the hunk during a motocross race in California.

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