Lisa Kudrow has reignited one of TV’s longest-running debates.

On Monday’s episode of “The Tonight Show,” host Jimmy Fallon asked Kudrow about what he’d heard was her new take on the enduring “Friends” question of whether Ross and Rachel (played by David Schwimmer and Jennifer Aniston) were really “on a break” from their relationship when Ross slept with another woman, after becoming jealous of Rachel’s colleague Mark.

“Yeah, I’m afraid now to bring it up,” joked Kudrow, who played Phoebe Buffay on the hit NBC sitcom, which ended in 2004.

Fallon pushed her for an answer. “This is scandalous. Get ready for some scandal — some tea. What is your take? Were they on a break?” he asked.

“Well, no,” Kudrow replied, prompting a loud reaction from the audience.
