Lauren Conrad Does ‘Letterman’

I can't seem to flip the TV channel without seeing Lauren Conrad this week!

Lauren didn't play much of a role in last night's mind-numbing episode of "The Hills." Instead, the focus was on her BFF Audrina Patridge, who admitted once again that she just can't seem to get over Justin Bobby. Ugh, enough already!

Thankfully LC had more to say when she paid a visit to "The Late Show With David Letterman." The reality hottie bonded with Dave over their mutual distaste for "Hills" villain Spencer Pratt. Plus, Letterman may have also gotten to the root of why she seems to have such trouble maintaining friendships. Check it out:

And don't miss Lauren's appearance as herself tonight on the season finale of ABC Family's "Greek."
