Kim and Kris both donned LBDs as they joined a host of stars at the Charlotte Tilbury beauty launch party at The Grove on Thursday night (9 October).
While 58-year-old Kris opted for a long-sleeved lace dress, Kim kept all eyes on her thanks to her mid-length, cut-out panel frock.
She was showing some serious side boob!
With flawless make-up, the mother-of-one had her hair styled into a bun, and teamed her daring dress with a pair of nude Givenchy heels.
It seems Kim was keen to make an impression from the back too, and showed off her famous derrière as she struck an over-the-shoulder pose for waiting photographers.
Despite leaving baby North at home, Kim looked like she was in the party spirit, as she and Kris rubbed shoulders with industry professionals.
Also in attendance at the glitzy beauty party was TV presenter Cat Deeley and singer Lily Allen.
