Gwyneth Paltrow admitted to trying ecstasy on "Watch What Happens Live" on Thursday night, January 15. The "Iron Man" actress made the revelation while being quizzed by Andy Cohen during the Plead the Fifth segment.

During the segment, Gwyneth was allowed to refuse to answer one of three personal questions asked by Andy. The first question was about a "frenemy" the "Shakespeare in Love" actress wrote about in an essay she posted back in 2009. Andy skipped over the question because the person wasn't famous.

The host then asked Gwyneth whether she would rather be stuck in an elevator with Jennifer Garner or Angelina Jolie. The 42-year-old actress then chose Angelina because she already knew and liked Jennifer and she would love to learn more about Brad Pitt's wife.

Andy then asked the third question to Gwyneth, "What is the hardest drug you've ever taken?" to which she replied with a smile, "Ecstasy." Andy then said, "Very good. She didn't plead the fifth everybody."

Gwyneth was promoting her upcoming movie "Mortdecai". She stars along with Johnny Depp, Ewan McGregor, Olivia Munn, Paul Bettany and Jeff Goldblum. Directed by David Koepp, the action comedy flick is scheduled to hit U.S. theaters on January 23.
