There are no secrets between the Kardashian sisters.

Speaking to, the three women -- Kourtney, 32, Kim, 30, and Khloe, 27 -- poked fun at Scott Disick, 28, who leaves little to the imagination when he goes commando on their hit E! show.

"Honestly, it's way too much," Kim said. "He has to start wearing some tighty-whities."

Kourtney raved about Disick's manhood, proclaiming: "It's like an elephant's trunk!"

Khloe seemed less impress with Disick, who often joked that he was "trying to compete" with her husband Lamar Odom, 31.

In the midst of their interview, Kourtney admitted that she received a Google alert regarding her boyfriend's penis.

"We went on a date night in the Meatpacking last night, so the story said, 'The Meatpacking District isn't the only thing packing meat!'" Kourtney said. "Scott was wearing a suit with no underwear last night, so you could see, like, something."

A grossed out Kim replied: "What?! Like, that's not normal. We have got to buy him some underwear for his birthday or something. This is freaking me out!"
