Kim Kardashian joined her sisters Kourtney Kardashian and Khloe Kardashian and their mother, Kris Jenner, for a rare foursome appearance on Chelsea Lately on Monday night. Jenner and comedian Russell Brand filled in for Chelsea Handler on April 8.

Jenner, 57, brought up Amanda Bynes' recent bizarre behavior and tweets during her opening monologue.

"So Amanda Bynes is apparently continuing with her public breakdown," Jenner said about the former Nickeloden star. The Kardashian matriarch then read out loud a news report about Bynes from a newspaper along with a series of recent tweets from the What I Like About You actress.

"I'm suing every blog saying I was kicked out of gymnastics. What is wrong w/ u people? What would u do if u found fake stories about u?" Jenner read from Bynes' Twitter account.

"Well, Amanda, welcome to my world," Jenner joked.

The Kardashian sisters then gave their opinions on Bynes' recent dramatic makeover.

"Am I the only one that is obsessed with her new makeover?" Kim asked her mother. "I think she looks amazing. With the blonde hair and those nails?"

"With all those extensions and makeup, you would think she looks hot," Khloe told Kim. "She does wear fishnets to the gym, I don't think that's abnormal. I love it."

Kourtney said that she "liked" the picture of Bynes wearing the blonde wig.

"I can't make fun of her wearing fishnets to the gym, because this is what I used to wear to the gym in the early nineties," Kris said. The Keeping Up With The Kardashians star then presented a picture to the audience of herself with her husband, famed Olympian athlete Bruce Jenner.

Bynes must have heard that the Kardashian sisters paid compliments to her makeover because she commented about it on Twitter.

"I love the beautiful Kardashian sisters!" Bynes tweeted. "I wish E picked better photographs of me! I feel pregnant when I'm fat! I'm working out constantly!"
