Brunette straight-to-DVD movie star-to-be Audrina Patridge celebrated her 23rd birthday at the LAX Vegas club with her mother and a group of friends that didn’t include her buddy from The Hills, Lauren Conrad.

When Lauren was asked by Us Weekly why she chose not to attend Audrina’s bash, she said, “Obviously there is tension and other things going on.”
