Jimmy Fallon reminded Jessica Biel that she made shady comments about NSYNC, the boy band that her husband, Justin Timberlake, was a part of – and she had a priceless reaction.

The actress appeared on NBC’s “Tonight Show Starring Jimmy Fallon” on Tuesday and said she wasn’t a fan of NSYNC or the rival group Backstreet Boys when she was younger because she was more interested in “old-school stuff.”

“I was listening to theater productions,” Biel said. “I was listening to ‘Rent.’ I, like, knew every word of ‘Rent.’ I was listening to Motown. I was listening to old-school stuff. I, like, lived under a rock. I wasn’t into pop-culture music.”

Fallon went on to show viewers footage from a 1999 interview with E! News where Biel was asked whether she was a fan of NSYNC.

"To be honest, I don't really listen," she said.

She added: "I mean, I know of them, of course, and I've heard of them, and I've heard the music. I don't think I own any of their CDs. I'm not a huge fan. But, I mean, cool, I guess."

"I'm screwed now," Biel told Fallon after watching the video. "The attitude!"

The "Limetown" actress said that even now, having been married to Timberlake for seven years, she's still not familiar with NSYNC's music. Biel recalled recently playing a game of truth or dare with her friends in which she was asked to sing a track from the group.

"I couldn't," she said. "I only know three words - bye, bye, bye - which is, I guess, one word three times."

Biel said that Timberlake "coached" her through singing another song from the boy band but that the experience was "really humiliating."
