Before turning 43 on Saturday, the creator of SKIMS held a star-studded birthday party on Friday night at Funke restaurant in Beverly Hills. As she arrived at the Los Angeles restaurant with family and friends, Kim came out in a vivid red fitting dress with cut-outs and ties at the sides. For her birthday outfit, the Kardashians opted for orange strappy shoes and black sunglasses.

Khloé, Kendall, Kylie, and mom Kris Jenner also made an appearance in similarly stunning outfits, as did Kim’s sister. Kendall stood out in a floor-length leopard print dress with long sleeves, while Khloé, 39, opted for a white halterneck little dress with matching pumps and a clutch.

The younger Jenner sister Kylie, 26, was also seen arriving at the event wearing a strapless black leather mini dress with zip detail, so the model, 27, wasn’t the only Jenner sister in attendance. While this was going on, Bieber, 26, a close friend of the Kardashians, arrived at the party wearing an oversized jacket and a tan and brown ensemble from head to toe. Hailey Bieber, Kimora Lee Simmons, Lauren Sanchez, and Ivanka Trump were among the other guests spotted arriving at the celebrity-studded birthday celebration.
