Kourtney Kardashian and Addison Rae Twin in Hot Pink Thongkinis

Korutney Kardashian and social media personality Addison Rae showed off matching hot pink Skims bikinis over July 4 weekend, posing for a series of selfies poolside. The duo, who have been friends since 2020, were sporting the swim brand's classic triangle top and thong bottom in the perfect Barbiecore shade. Both women opted for natural, makeup-free looks with wet hair, as if they'd just taken a dip, and all four photos showed Kardashian's growing baby bump front and center — including one lounge chair shot that featured the 44-year-old Poosh founder in a denim Prada bucket hat. Meanwhile, Rae, 22, wore delicate gold chain necklaces and earrings, plus a white ruffled eyelet scrunchie on her left wrist. Their skin-baring swimsuits — though perhaps not the most patriotic in color for the holiday — were certainly some of the most eye-catching posted from the celebrity set on Instagram.

Last month, Rae suggested pink is her go-to color in swimwear when she posted a TikTok in a rhinestone-covered two-piece by Seashell Bikini. A scroll through her Instagram will also confirm she's a fan of the thongkini silhouette, with the cheeky trend only gaining more steam as the summer rolls on. Kardashian, on the other hand, recently enjoyed a gender reveal party with husband Travis Barker, where she sported a baby-blue, skintight catsuit to allude to the idea that she's expecting a boy. She also rocked an ultra-strappy green bikini while relaxing with her family on June 23.
