One night of rekindling a high school, reality TV romance by making out in public evidentgly wasn't enough for Lauren Conrad and Stephen Colletti.
Lauren and Stephen made out at Las Vegas' LAX club on Sunday, December 30, the night after they were spotted flirting and kissing at Central in L.A.
Conrad (wearing a HOT strapless, knee-length silver dress with an oversized bow on the front) arrived at LAX with The Hills co-star / roommate Audrina Patridge and high school BFF / Laguna Beach co-star Lauren "Lo" Bosworth.Â
Thirty minutes after she rolled in, Stephen Colletti â€" Lauren Conrad's ex from the olden days on Laguna Beach â€" showed up and immediately joined her table.
The duo were inseparable for the rest of their night out, touching one another and whispering. At one point, Lauren Conrad and Stephen Colletti got hot and heavy as she positioned herself between his legs - hot stuff! - as they kissed.
Colletti, who recently split with Heroes hottie Hayden Panettiere, then kept a close eye on Conrad when she took pictures with fans or celebrities - especially when she was being photographed with the likes of Dave Navarro.
