Lauren Hits The Gym!

And she still has that annoyed look on her face afterward!

C'mon, LC... exercise may be exhausting, but it does put you in a happy, healthy mood. So why do you still have a dour expression? Maybe from hanging out with Lo too much? Or maybe because she'll be leaving The Hills soon!

The reality TV star tells Extra that while she "loves this show so much," she's also "ready to kind of walk away." Way to be vague, Lauren!
