Last weekend kicked off the opening of Pearl at The Palms, where Gwen Stefani was the first to break in the state-of-the-art concert venue on the first date of her 2007 tour.

No doubt (just had to do it), Katie was there. She told us this about the evening, “It was an amazing show. I can’t think of a better place to see a concert and Gwen Stefani, well, I’ve always been a fan, so I had an unbelievable time.”

Also walking the red carpet were Luke Wilson, The Hiltons, Bruce Willis, Panic! At the Disco, Nicolette Sheridan, Tommy Lee to name a few. After a private reception, the guests were led to their luxury skyboxes inside the new theater, which include private bars, lounges and restrooms. Swanky!

After the concert, the party moved on to Moon nightclub in the Fantasy Tower.
