There's always something going on in Sin City, and last night (November 8), a bevy of celebrities were spotted out at TAO nightclub's 3-Year Anniversary Celebration.
Gracing the red carpet and mingling about The Venetian hotspot were stars including Kate Walsh, Ellen Pompeo, Taye Diggs, Jenna Fisher, Amanda Bynes, Stacy Keibler, Denise Richards, along with numerous others.
As for Miss Pompeo, she also happened to be celebrating her birthday, as well as her and husband Chris Ivery's 1-year wedding anniversary, staying in a "plush suite" at the Palazzo over the weekend.
"They wanted to do something special," a source told E! News, "but didn't want to go too far because of Ellen's filming schedule."
