On Karanikalaou’s actual birthday, Jenner posted a heartfelt message to her on Instagram, calling her “a real one,” justtwo days after she was spotted at the same nightclubas ex-friend Jordyn Woods, as well as sisterKhloé Kardashian’s exTristan Thompson.
Jenner and Woods were reportedly both there to celebrate Karanikalaou’s birthday, although it’s unclear why Thompson visited the hotspot too, according toTMZ. The outlet also reported that Woods arrived to the party with palJaden Smith, who is also friends with Jenner.
However, Woods was not featured in any of the clips Jenner shared from the bash online, so it is unclear whether or not they interacted at the West Hollywood nightclub.

Jenner and Woods were best friends since their high school years, but their relationship was severed in the wake of Woods’cheating scandalwith Thompson. While sources told PEOPLE Jenner wasinitially tornabout rekindling their friendship, it appears she has since moved on.
“Kylie has had a very hard time moving on from their friendship. But not being able to rely on Jordyn’s friendship has actually been great for Kylie,” a source previouslytold PEOPLE, adding that while the pair are “occasionally” in touch, their relationship will never be the same.
“Kylie is still in contact with Jordyn occasionally, but they are never going to be best friends ever again,” said the source. “Kylie has moved on and seems very happy.”
