The Kardashians are known for their love of a string bikini but it's rare to see matriarch Kris Jenner in her swimsuit – until now.
The 68-year-old posted a carousel of pictures with best friend Shelli Azoff, whose birthday Kris was celebrating, and one stood out to fans as it featured the longtime friends in the clear blue waters looking gorgeous.
Kris wore a black and white polka dot bikini top, paired with a black sun hat and black sunglasses with pearl detailing, while Shelli rocked a black one-shoulder suit.

"Happy Birthday to my amazing BFF Shelli! @shellibird1," Kris captioned the post, adding: "We’ve shared so many incredible memories over the last four decades, and I’m so grateful for your friendship and the love, laughter, joy, support, fun, and the endless surprises you have brought to my life."

"You’ve been there through everything, and I can’t imagine life without you. Thank you for being by my side all of these years. I cherish you and love you more than you know!! Here’s to many more adventures and beautiful moments together!"

Khloe Kardashian was among the famous faces to comment, sharing an in-joke as she wrote: "Happy birthday Smelli!!!!!! I looooooove you."

"Botox and fillers and laser [treatments] and things like that. I had a boob job in the '80s after four kids because gravity took over," Kris once shared in 2015, revealing she had later had a breast reduction, "a couple of years ago" as she, "felt they were too big".

"We grew up together and so we're going through this chapter now and we love it," Kathy, who has eight grandchildren, said. "It's just like family, everyone's kids are growing up like cousins."
