THEN: Jen Bunney, Season 1
Jen Bunney was Lauren Conrad and Lo Bosworth’s bubbly friend. She played a bigger role on The Hills than on Laguna Beach, but she did tell LC that her Cabo skirt was a little "poofy." She was the reported cause of a falling out between Lo and LC, which caused them to not speak for two years. She also hooked up with Brody Jenner — per Spencer and Heidi’s request — thus ending her friendship with LC.
In the later seasons of The Hills, she was Heidi’s only female friend.
