The Keeping Up with the Kardashians stars, ages 39 and 40, respectively, stepped out for the event, hosted by Lynda Resnick and Cassandra Grey, at a private residence on Wednesday (November 20) in Beverly Hills, Calif.

That same day, Kim and Kourtney Kardashian sat front row and center at Madonna‘s show at The Wiltern in Los Angeles, ET reports.

At one point, Madonna sat down with Kim and asked in front of the audience whether or not she was having a good time, to which Kim replied, “It’s so surreal. I’m with my sister, Kourtney, and she used to play your records all the time when we were young.”

Madonna and Kim then talked motherhood, with Kim revealing that she and her kids go to bed early. Madonna said, “I don’t know how you wake up early and look so beautiful. I look like s–t in the morning. You must be drinking the right juice.”

“It’s eye masks,” Kim shared.

When Madonna offered Kim a sip of her beer, Kim Kardashian told her that she’s “not a big drinker.” Madonna then said, “Neither am I, but I’m so dehydrated. I’ll drink anything. Well, I hope you’re having a great time. And if your sister misbehaves, I’m bringing her onstage with me.”
