Teri Hatcher was the surprise guest vocalist

At the 11th annual Lupus LA Orange Ball held Thursday, host Fred Willard revealed what any good partygoer in the City of Angels has accidentally experienced at least once.

“I went to the Beverly Hills Hotel and the Beverly Hilton before I finally made it here to the Beverly Wilshire,” he joked. “They need to call this hotel the Warren Beatty instead. Occasionally, Warren would wander downstairs in his robe, in between having sex in his suite. I’d never get it wrong if they called it the Warren Beatty.”

Teri Hatcher was the surprise guest vocalist. “I’ve got the girls hanging out tonight,” the divorcee vamped in a plunging outfit. “I need a boyfriend! It’s been a long time.”
