Is Audrina Patridge... Preggers??!

Do we spy a possible baby bump??

This pic was taken on Saturday night. Audrina was sporting a cute pink dress — an what looks like a a cute baby-fied tummy!

That’s pretty unusual for a girl who’s known for her incredibly flat stomach and killer bod.

What do U think?! Has she been knocked up?? Or maybe just bloated?
