Lauren "Lo" Bosworth donned spandex to hit the gym this week. Where were gym buddies Lauren Conrad and Whitney Port? We always see them on The Hills with their trainer, but I suppose that L.C.'s busy schedule is hard to follow, with her new books, filming, and traveling. Since we see the girls around each other so much, it's almost weird when they are alone.

Lo isn't helping her rep with that expression. Smile, Lo, smile-- before it's too late.
