Kim Kardashian, Kourtney Kardashian and Khloe Kardashian joined their mother, Kris Jenner, for a rare foursome appearance on Chelsea Lately on Monday night. The group sat for chat with Russell Brand who filled in for Chelsea Handler on April 8.

The roundup of the Armenian beauties-who appear together on Keeping Up With The Kardashians- inspired Brand to say he would like to sleep with the three Kardashian sisters.

"I'm vulnerable to the concept of a KKK threesome," Brand told the Kardashian sisters.

"Well, I heard pregnant p***y is the best p***y," Khloe replied.

"I think pregnant women are radiant and beautiful and the idea of lactation is an interesting one," Brand joked. "A limitless, foaming river of milk and orgasm."

When the sisters wondered out loud why Handler didn't appear on her show, Kourtney joked: "I'm sure she's doing something really important, like drinking."

"Or having sex with somebody that she just met," Khloe added.

Kim, who has been on the receiving end of Handler's jokes about her for several years, joked that she and the late night talk show host "now fit into the same size dress!"

The sisters then said together in unison: "F**k you, Chelsea!"

On Sunday, shortly after the season 3 finale of Kourtney & Kim Take Miami, E! aired a commercial to promote the upcoming eighth season of Keeping Up With The Kardashians. The visit to Chelsea Lately is the beginning of the Kardashians and Jenner promoting the show. KUWTK season 8 will premier on June 2.

Jenner is set to debut the first season of her own daytime talk show, Kris. The new show will get a six-week test run and will air on Fox this summer, according to ABC News.

"This is something I have wanted to do all my life so it's definitely a dream come true!" Jenner said in a statement.

Chelsea Lately airs weeknights at 11/10c on E!
