Cloris parties on

CLORIS Leachman, who turns 91 on April 30, is still the life of the party. Leachman was the center of attention at a bash for her new Starz series, “American Gods,” on Thursday in LA, where she partied late into the evening — bumping and grinding with other partygoers. “She was one of the last to leave and joked on the way out that she was going to another bar,” says an attendee. “People were ditching their own VIP tables to hang out with her. She was bumping and grinding with her guests.” We’re told Leachman last year “requested — and got — a cake from friends that said, ‘I’m 90 f - - king years old.’ ” We’ll see how they top that this year.
