What Happened in Vegas?

With us headed to Las Vegas on Thursday, I found all the comings and goings of these celebrities interesting (especially where Channing Tatum was hiding) . I'm sure we won't see any, however. They avoid me like the plague.

Nick Lachey enjoyed a boys night out with several sporting pals, including Matt Leinart and Reggie Bush at Hollywood hotspot MyHouse on Friday night. The team took over the sunken living room VIP area and in true sportsman style kept trying to out spend each other with bottle after bottle. Meanwhile, Reggie's better half (aka Kim Kardashian) and her sisters made it a family outing for the night and were treated with sparklers and bottles of champagne and vodka.

Adam Sandler, Kevin James, Jonathan Loughran and Ray Romano hit up The Mirage's "The Beatles Revolution Lounge" on Friday night after Romano's performance at the Terry Fator Theater. The comedic crew drank Amstel Light and downed shots of Belvedere, which were probably contributing factors to the antics that ensued. While James was doing handstands on the table, Sandler was approaching each of the go-go dancers and telling them that he was "scouting" actresses for his upcoming movies. The gorgeous ladies ate it all up but funnily enough, Sandler never ended up actually casting the role. Prior to their eventful evening, the guys fueled up at Stack Restaurant & Bar.
