Kylie Jenner, ex Travis Scott reunite for elaborate birthday bash

Kylie Jenner and Travis Scott reunited for a birthday bash over the weekend.

The reality star, 28, and her rapper ex-partner celebrated a landmark in both their children's lives. The former couple came together to mark their daughter Stormi's 8th birthday and their son Aire's 4th birthday. Stormi was born Feb. 1, while Aire was born Feb. 2.

In a series of shots posted to Instagram stories by Jenner's sister Khloe Kardashian, cookies with the children's faces could be seen, as well as Labubu-themed party plates. Several other shots showed balloons.

In videos posted to X, Jenner and Scott could be seen singing happy birthday to their children as fans readied to cut into the cake. Jenner, in tight black pants and a white top, sings into the microphone, one of the children on her hip as Scott videos with his phone. The background, a warm desert theme, shows red rock sculptures, a palm tree and cacti.

The onetime couple, who began dating in April 2017, shocked fans with the news of Stormi's birth in 2018, after keeping Jenner's pregnancy a secret. Though the exact timeline of their split remains unclear, People reports that they called it quits for a final time in late 2022 after welcoming Aire that same year.

Jenner has since begun dating film star Timothée Chalamet, in a once-hush-hush but now public relationship. The two have been spotted on several awards show carpets this season as Chalamet is recognized for his performance in "Marty Supreme."

Chalamet recently thanked Jenner following his win at the Critics Choice Awards.

"Lastly, I'll just say, thank you to my partner of three years, thank you for our foundation," he said as the camera panned to Jenner. "I love you. I couldn't do this without you. Thank you from the bottom of my heart."
