Matthew Perry denied reports Thursday that his "Friends" co-stars slept together.
"I think there was no sex between any of them, or else I was really missing something," he told host Andy Cohen. "I [personally] did not."
Rumors swirled in February 2016 after the "Friends" stars, minus Perry, reunited to honor director James Burrows.
David Schwimmer appeared to confirm there were on-set flings after Lisa Kudrow denied there was a "no sex" rule in their contracts.
"Well, that was broken!" the actor said of the alleged clause.
"Friends" had a 10-season run from 1994 to 2004.
Perry reunited with Schwimmer, Kudrow, Jennifer Aniston, Courteney Cox and Matt LeBlanc at an informal gathering earlier this year.
"We have convened, privately, for dinner, and it was great," Kudrow told "Today" in February after denying there will be a formal reunion or revival.
"It was really fun. We had such a good time. It was hilarious. We were laughing nonstop."
He last starred in the Reelz miniseries "The Kennedys: After Camelot" with Katie Holmes.
