Kathy Griffin rings in 65th birthday by baring her abs in red hot bikini

Kathy Griffin celebrated her 65th birthday by showing off her washboard abs.

The comedian appeared on Sherri Shepherd’s talk show Tuesday wearing nothing but a bright red bikini and a pair of gold pumps.

“Oh. My. God,” Shepherd screamed as Griffin strutted on to the stage with cheers erupting from the audience.

Griffin showed off a few dance moves, displaying her toned figure and even pointed at fans to “take a look” at her butt.

After doing a spin for the crowd, she covered up in a teal-colored robe — which she later revealed belonged to her late friend Joan Rivers — and sat down for her interview.

The Emmy winner reminded the audience that she just turned 65 years old, and that her age wasn’t stopping her from showing off her enviable physique.

“You look amazing,” Shepherd gushed. “What a birthday present. I just want to give you your flowers because it’s such a beautiful birthday gift to yourself, your health and the perks, and you look amazing.”

“I was shaking my cellulite for you,” Griffin joked, before the talk show host applauded her for “own[ing] it.”

Noting how “stunning” and “sexy” she looks, Shepherd then asked Griffin if she was “still looking for a man on a dating app.”

The “Kathy Griffin: My Life on the D-List” star finalized her divorce from her second husband, Randy Bick, back in January after nearly four years of marriage.

Griffin revealed she’s on four different dating apps — including the exclusive Raya — where she hit up “that whore” John Mayer, whom she matched with “immediately.”

“And so I got his number and I texted him and I said, ‘Hey John, it’s your old pal Kathy Griffin’ — he can’t stand me, of course — and I said, ‘We were matched on Raya and if you know what’s good for you, I put out on the first date.’”

After sending the risqué text, Griffin admitted that Mayer, 48, “wisely” left her on read.

Griffin’s jaw-dropping appearance comes months after she confirmed she got a third facelift. Fans had been questioning her “very taut” look before she ‘fessed up to the procedure.

“This is my third, yes,” she said about her recent facelift on her “Talk Your Head Off” podcast in August.

“I know that’s so vain!” she continued. “I’m so vain for no reason. No one has ever gone to a Kathy Griffin show to see her beautiful, youthful face. You come to hear my jokes, which is what I want.”
