Pauline Chalamet is keeping up with Kylie Jenner's career milestone.
In fact, the Sex Lives of College Girls actress was seen supporting her brother Timothée Chalamet's girlfriend as the Kardashians star made her Paris Fashion Week modeling debut Oct. 1.
Pauline, 32, could be seen sitting in the crowd at the Coperni show, rocking a knee-length, oversized beige button up coat and olive green boots as she watched Kylie, 27, close out the runway show at Disneyland Paris in a black corset ball gown with matching long-sleeve gloves.
And in a video posted to social media, Pauline could be seen hugging Kylie at the show.
Both Kylie and Pauline have a lot to celebrate these days, as The King of Staten Island star recently revealed that she welcomed her first baby, telling friend Greta Gerwig at Stella McCartney's Paris Fashion Week show Sept. 30 that she had given birth "three weeks ago."
Pauline has not publicly revealed the identity of the baby's father, although in video footage from the exchange she could be seen introducing him to Greta.
Sadly absent from the fashion fest was Timothée, who is currently in New York and looking unrecognizable on the set of his upcoming film Marty Supreme.
He and Kylie were last spotted together in August enjoying a trip to the Bahamas to celebrate her birthday. And despite being together for over a year, the Kylie Cosmetics founder—who shares kids Stormi, 6, and Aire, 2, with ex Travis Scott—enjoys keeping their romance out of the spotlight.
"Privacy is so important to me in life," she told British Vogue in August. "I learnt at such a young age how to deal with all of this in the best way for me. So I don't go crazy, if I am being honest."
Timothée echoed her desire to keep their relationship private, although he knows that is often a difficult task for someone in his position.
"I can't say that this stuff doesn't matter, because my intense fandom has led me to where I am," the Dune star told GQ in 2023. "Sometimes, people are going to be hella confused when you say you're trying to live a private life."
