Is Holly Madison Pregnant?

Yes, folks, the celebrity gossip mill is in full swing on this one.

Simply based on a photo - seen here - of Hugh Hefner patting the belly of his main girlfriend, Holly Madison, rumors are swirling that she's carrying his child.

A bit presumptive? We think so. But a source told Star Magazine: "Holly's just dying to get pregnant and marry Hef so he can be all hers."

Such a development would certainly upset the other Girls Next Door - and we doubt it's actually the case. But we'll report more on these rumblings as they come in.
