"She looks sick," Ricki told Access Hollywood on Tuesday. "I mean, man, she showed me up, didn't she?"
Valerie, 48, showed off her new figure on the April 6 cover of People after losing almost 50 pounds.
"She looks great," Ricki continued. "She looks a lot better than I would look in a bikini."
But would Ricki follow Valerie's lead and pose for her own bikini photo shoot?
"I don't wear bikinis. Trust me, nobody wants me in a bikini," she said. "But I do naked pretty well. Everyone will just have to use their imagination on that one."
