Just days after breaking up with boyfriend Ryan Cabrera, Audrina Patridge returned from her sexy Costa Rican vacay -- with ex Justin Bobby!
Audrina hit the Central American country with the rest of The Hills cast including Kristin Cavallari. They famously fought over the hottie during last season of The Hills, but have become fast friends since they both ditched the dirty hot biker boy.
We spotted the girls returning together Friday night, but we didn't notice Justin Bobby following behind Audrina -- until now!
But with this new little twist in the mix, we wonder if the truce ended the moment Justin Bobby came back, or if they all kiss and made up in the end!
Although Kristin doesn't exactly seem like the type to want to share...
