Bette Midler got crazy applause at PURE nightclub, after her first Vegas performance at Caesars Palace.
Lance Bass and boyfriend Leo, Siegfried & Roy mingled with the ridiculously-straight Dog Chapman and wife Beth. Midler was applauded as the diva made her way into the club.
Federal agents raided PURE earlier in the day. The IRS has some questions about ever-pesky taxes the club may or may not have paid.
