Pink has hinted she's pregnant.

The singer and her motocross racer husband Carey Hart already have daughter Willow together, who turns three next month.

Recently sources claimed the pair were expecting a second child and now Pink, 34, seems to have confirmed that the speculation is true.

"I love that every time I find a box of Girl Scout cookies I'm pregnant. Guilty: I'm having a thin mint:) (sic)," she cryptically posted on Twitter.

Earlier this month an insider told Us Weekly that Pink and 39-year-old Carey were spotted together and that he was tenderly rubbing the singer's belly. Apparently Pink moved his hand away, in an attempt to keep the alleged news a secret.

β€œIt's the perfect time for another one,” an insider added to the publication.

In the past, the So What singer has claimed that she wants five children. She suffered a miscarriage before falling pregnant with Willow, which could be the reason why she has kept the supposed pregnancy under wraps until now.

β€œ[I] was just really nervous and I have had a miscarriage before but if I was going to talk about it with anyone, it was going to be with you," she revealed during a 2010 interview with Ellen DeGeneres.

Pink could have two little superstars in her family if the happy news is true. She keeps her Twitter followers up to date with Willow's latest antics and recently revealed she's turning into quite the budding singer.

"Putting my little girl to bed tonight while she sings herself to sleep... "So what... I'm a rock star... And I'm havin fun and so what ...." (sic)" she proudly wrote.
