During her Thursday appearance on Andy Cohen's "Watch What Happens Live!," the 42-year-old actress agreed to play "Plead the Fifth" and respond to three personal questions, one of which she could opt out of answering.
Cohen first asked Paltrow to name a "frenemy" that she wrote about in a Goop post, but the actress decided to pass on revealing that person's identity. She said the post didn't involve anyone famous.
Up next, the host asked her to choose between being stuck in an elevator with one of her exes' wives -- Ben Affleck's wife Jennifer Garner or Brad Pitt's leading lady Angelina Jolie. While Paltrow confessed that she's closer with Garner, the Mordecai actress ultimately chose Jolie because she'd love to know more about her.
The third question is when it got really good. Cohen asked, "What is the hardest drug you've ever taken?"
"Ecstasy," Paltrow answered with a smile.
Are you surprised by the actress' confession?
