When Did Audrina Become A Mom?

Well, we hope she's not one - yet!

The Hills hottie Audrina Patridge was spotted up in Hollywood yesterday and she was not alone... girl was carrying a baby! We're sure it's a friend's or a family member's - or something having to do with her reality show - but still! Everyone's getting preggers these days so who knows!

Think Audrina would make a good mom?
