[Lauren Conrad] was making out with Stephen Colletti, her ex from their days on Laguna Beach and a host for MTV, at LA's Central on Saturday night.

After arriving together Conrad and Colletti stayed close to each other all night, flirting and chatting. They were spotted making out by the bar after Colletti carried her there from the dance area.

Rebecca: omg
if you watched Laguna Beach, you'd understand
though you're "too mature" for that
me: what's the big deal?
did they hate each other?
Rebecca: They dated in high school
off and on
he sort of played her, and then he realized that after high school, girls like men who can shave
so then he was really into her
and she was like so over it
me: THAT'S MY LIFE!!!
Rebecca: Hello, that's why it's called reality tv
