Khloe sat down with Andy Cohen for the no-holds-barred conversation, where she opened up about her past sex tape.

"I've definitely recorded myself having sex with my ex-husband," Khloe said, referring to Lamar, "But not like, talking to camera."

While Khloe could have been be talking about any number of celebrity sex tapes, she might have been making a subtle dig at her sister Kim for her infamous sex tape with rapper Ray J, released years ago.
