Kylie isn't the only bombshell supporting Hailey's Rhodes line, as her former BFF Jordyn Woods, whom she recently reconciled with, showed up at a Rhodes event last week and took a few snaps with Hailey.
The brunette beauty rocked a pink bodysuit and a faux fur stole alongside Hailey, who stunned in a tiny black dress.
The picture-perfect pair even blew a kiss for the shutterbug, as Jordyn captioned the snap, 'It’s a @rhode kinda night.'
Jordyn and Kylie confirmed they reconciled their friendship through a TikTok video last month, marking their first public appearance together on the platform.
In the video, Kylie captured her trip to Acne Studios with a bout of retail therapy and took selfies with Jordyn in front of a full-length mirror.
It comes less than two months after their first public sighting together since 2019.
The friends endured a period of estrangement following a cheating scandal, where Jordyn kissed Tristan Thompson while he was in a relationship with Khloe Kardashian.
