Kylie Jenner & her best friend Stassie Karanikolaou had a good time hanging out in a hot tub.

Jenner told everyone on her Instagram Story about the beautiful time she had with her best friend.

The make-up mogul shared a stunning photo of the two of them posing beside a luxurious Jacuzzi bathtub.

They were dressed in black bikinis that exposed their hot bodies.

Karanikolaou showed off the diamond stud she had put in her navel piercing.

Jenner tagged herself as well as the YouTube channel "Cold Plunge Girls."

At first, the mom of two worked out with her best friend and some other friends.

Fans suspected the make-up mogul & her BFF were lesbians.

They also thought Jenner and Travis Scott, the father of her child, might have broken up.
