Lauren Conrad and Audrina Patridge slipped into fancy party dresses to ring in the New Year in San Diego, Calif. And what a night it was. LC was looking way too partied out by the end of the night... but had plenty of fun kissing some guy.

A guy not named Stephen Colletti!

Check out the photo evidence from New Year's below. You can make out Lauren Conrad making out with some dude in the background - and it ain't Stephen!

And so the roller coaster of love continues for Lauren Conrad. Brody Jenner and Jason Wahler, Gavin Beasley and Josh McRoberts... it's near impossible to track who's flirting and getting to first base with The Hills star. But fun to try!

We can only hope that The Hills cameras were rolling during all of Lauren's adventures with the boys â€" and that Whitney Port gets a little more air time!
