'The Mortified Sessions': Cheryl Hines And Margaret Cho Reveal All (VIDEO)

On Sundance Channel's "Mortified Sessions," celebrities reveal their dirty laundry. From how they learned about sex to childhood crushes, they're not holding anything back. On the upcoming new episode, "Suburgatory" star Cheryl Hines and comedienne Margaret Cho are next to spill their secrets.

When Hines, pictured above, was a child, she didn't have the nicest nickname.

"I physically had warts, a lot of warts," Hines says in the Jan. 2 episode. "So they called me, 'Worry Wart.' It was mean, because I did indeed have warts, and I did worry a lot."

For Cho, pictured below, realizing she wasn't white was a shock.

"When I was maybe six, I was really angry that I was not white. When I realized I wasn't white I was so furious ... I still have deep fantasies about being white -- it must be so relaxing to be white. I wish I could go to the spa and just be white for an hour," she said.

"The Mortified Sessions" airs Mondays at 8 p.m. EST on The Sundance Channel.
