Audrina Patridge and Lauren Conrad Wet for Brody

With friends like these, who needs bros?

Reality-TV heartthrob Brody Jenner turned 25 last Thursday, and his Hills castmates Audrina Patridge and Lauren Conrad helped him commemorate the milestone in style, living it up at LG Villa Cabo in Cabo San Lucas, Mexico.

Nice to see that the on-again, off-again friends could once again set aside their differences for the sake of a pal. When push came to shove, they threw on their bikinis and partied down, and looked damn good doing it. They’ve had a lot of practice at that sort of thing.

The only thing that might have made the celebration more complete would have been a pint-size party boy in swim trunks. But it’s not always possible to have everything—not even for Brody Jenner.
