Biel, 37, donned a metallic jumpsuit and curly wig in a recreation of the 38-year-old “Bye Bye Bye” singer’s old school look at the Casamigos Tequila Halloween party in Beverly Hills on Friday, October 25.
Timberlake, meanwhile, came in costume dressed as a giant microphone. The couple were accompanied by four friends who were dressed as former ‘NSync bandmates JC Chasez, Chris Kirkpatrick, Joey Fatone and Lance Bass.
The Limetown star’s costume comes after a 1999 interview resurfaced of Biel shading Timberlake’s boy band. During an appearance on The Tonight Show Starring Jimmy Fallon on October 22, Jimmy Fallon, 45, played a video clip of Biel claiming that she doesn’t listen to their music, which at the time had become a phenomenon.
“To be honest, I don’t really listen [to them]. I haven’t really,” she said. “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.”
Present-day Biel admitted to Fallon that she still isn’t familiar with the group’s music.
“Not really,” she said. “I mean, listen, it became very clear to me just a month ago when we were with our friends. We were hanging out again in Italy somewhere. We were trying to play Truth or Dare, which is the dumbest thing to do with a bunch of late 30-year-olds. It’s a bad idea. Everyone knows each other’s truth, so it’s boring. So[,] we just played Dare, and my dare was I have to sing an ‘NSync song, all the lyrics, all the melodies, and I literally … I couldn’t. I only know three words: ‘Bye, bye, bye,’ which I guess is one word three times.”
She added that, although her husband tried to help her with the lyrics, the experience was still “humiliating.”
Biel and Timberlake began dating in 2007 and tied the knot in 2012. They are the parents of 4-year-old son, Silas.
