65, Wears A Bikini On 'Sherri' For Her Birthday: Watch!

The comedian, 65, looked incredible on Tuesday, Nov. 4, during an appearance on Sherri Shepherd 's talk show.

To the cheers and screams of the audience, birthday girl Griffin made her entrance on the show in just a bathing suit and a pair of gold pumps as Shepherd, 58, said, “Oh. My. God.”

An excited Griffin reminded the audience that she'd just turned 65 years old as she sat down to chat to Shepherd, by this time covered up in a teal-colored dress.

Griffin marked her milestone birthday with a reflective post on Instagram , sharing that she still feels like she's 25. Alongside a smiling selfie and the Beach Boys' track "Wouldn't It Be Nice," Griffin shared her birthday plans, which included a birthday flash mob party, taping episodes of her YouTube show and her appearance on Sherri.

Griffin's amazing appearance on Sherri came after she revealed back in August that she'd undergone a third facelift , explaining that she was “so vain” for wanting the surgery.

"It's my third,” she said. “I know that's so vain! I'm so vain for no reason. No one has ever gone to a Kathy Griffin show to see her beautiful, youthful face," she said, adding that the procedure was performed by Beverly Hills, Calif.-based celebrity plastic surgeon Dr. Ben Talei .

⁘There's a stitch in my chin, which you're probably not going to see unless you're under me, but not in that way,⁘ she joked.
