Chrissy Teigen never ever wears underwear. Not even when she's on a TV talk show wearing a mini dress. Not even during that time of the month.

In a super-revealing interview with Joan Rivers on E!'s Fashion Police on Friday, Aug. 9, the Sports Illustrated swimsuit model explained that she goes commando simply because she prefers not to wear panties. "I just don't, I don't like it," she succinctly told the stunned hosts, including Giuliana Rancic and George Kotsiopoulos, and fellow guest Ashley Benson.

When Rivers asked Teigen if she was currently wearing panties, the model, 27, replied in the negative. "I [just] got a nice a view," Kotsiopoulos quipped.

Shock turned to horror when Rivers probed John Legend's fiancee about what she does on "like, a heavy flow day." At which point, a clearly traumatized Kotsiopoulos yells out, "Oh, T.M.I.! T.M.I.! Stop! Stop it!" As Teigen began to explain what dancers in rap videos do in such situations, he again attempted to put an end to the raunchy discussion: "We're still talking about this?! Stop it!"
