Pink's rounded belly sparks pregnancy rumour!

Pink is known for her washboard stomach. But now this photo of her and hubby Carey Hart buying junk food at a gas station in Beverly Hills has gotten us wondering.

Her stomach is clearly more rounded than normal. Is this an early pregnancy, or did she simply have too big of a lunch?

Last December it was rumored that the two were ready to start a family and would start trying when she wasn't touring. Well, she's not touring now, sooo.....

I guess we'll find out in the coming weeks -- if it grows, its a baby...if not, well, then chalk it up as another false baby bump rumor.
