Kim Kardashian and her mom Kris Jenner attended makeup artist Charlotte Tilbury's VIP Beauty Launch presented by Nordstrom at The Grove in Los Angeles last night, and both of the ladies opted for sexy black dresses. Even though Kim is giving PMK some serious side eye in that left shot, she managed to one-up her in the cleavage (and leg) departments.

“Glam Girls! Celebrating @tilburymakeup new make up line launch! So proud of you!” Kim tweeted, adding, "Tonights glam @makeupbymario bronzy peaches & cream make up. Sleek slicked bun @robscheppy."

Other celebs at the event included Lily Allen, Liberty Ross and Keltie Knight.
