Pink is rumoured to be expecting her first child with biker husband Carey Hart.
The 31-year-old singer has been pictured frolicking in the sea at a Los Angeles beach this week wearing a filly black bikini which appears to reveal a tiny baby bump.
The picture follows reports by Us Weekly that she is 12 weeks pregnant.
Good Day LA co-host Jillian Barberie Reynolds wrote on Pink’s Twitter page: “Congrats on baby!! Ps. You know your man whispered it to us at dinner.”
But the So What singer has not confirmed or denied the rumours.
Pink, real name Alecia Moore, split from professional motocross racer Carey in February 2008, but rekindled her relationship with him a year later.
They remained close throughout the split and Pink even said their future might involve “beach babies and sunshine”.
Pink met Carey at the X Games in Philadelphia in 2001, and apparently proposed to him in 2005 during one of his races, by holding up a sign which read: “Will you marry me?”
The pair married in Costa Rica on January 7, 2006.
