Audrina Pines for Ex-BF
"Hills" babe Audrina Patridge has moved on from "Star Trekker" Chris Pine -- and is sucking face with one of her exes, BMX biker Corey Bohan.
The two -- who dated last August -- were caught swapping spit at Lavo nightclub at the Palazzo last night.
Could be worse ... at least it wasn't Justin Bobby.
