What happens in Vegas stays in Vegas.

Unless you happen to be seen by our staff!

In any case, at 4:11 AM Pacific Time this morning, a T.H. Gossip informant spotted Laguna Beach and The Hills bad boy Jason Wahler at the Golden Nugget hotel and cashino in Las Vegas. Wahler (pictured with ex-girlfriend and co-star Lauren Conrad) unfortunately escaped our spy before she could ask him any questions or snap a hot pic of his circa 1996 frosted hair with her camera phone.

What was he doing in Sin City? We have some theories:

• Partying.
• Playing $5-a-hand blackjack.
• Trying to hook up with girls.
• Talking like a neanderthal, attempting to act cool.
• Watching a payday loan shark masquerade as a card shark.
• Hanging out with Kevin Federline and Ron Jeremy.
• Searching for Ashlee Simpson's chin.

Okay, that last item has nothing to do with Vegas. We just threw it in there to be funny. But seriously, what the hell happened to that thing!?
