And the launch of Kylie Cosmetics’ Lip Kits was a real Kardashian family affair as she was joined by her sisters Kim, 41, Khloe, 38, and Kendall, 26, for the A-list bash.

Eldest sister Kourtney, 43, was also at the event in Los Angeles.

She wore a leather corset as she walked holding hands with her husband, Blink-182 drummer Travis Barker, 46.

It comes as Kylie wowed in a plunging silver bikini while cuddling up to her hairstylist, Jesus Guerrero, two days ago.

Kylie almost spilled out of her top, which featured a daring scoop neckline.

The mother-of-two appeared to go makeup free for the 𝓈ℯ𝓍y beachside photo.

She shared the shot on her Instagram Stories.

She captioned it: “Happiest 𝐛𝐢𝐫𝐭𝐡day to the most beautiful, loyal, kind, thoughtful, harworking!!! @jesushair love you forever.”
