On Friday night, the actress channeled Justin Timberlake‘s ‘NSYNC years while attending the star-studded Casamigos Halloween party in Beverly Hills, hosted by Casamigos founders Rande Gerber and Mike Meldman.
Biel, 37, stole the show in a metallic ’90s-inspired jumpsuit, white sneakers, tiny blue sunglasses, diamond earrings and, of course, a wig that resembled her husband’s short curls during his time in the iconic boy band.
Meanwhile, Timberlake, 38, who was one of the lead vocalists of ‘NSYNC from the band’s beginnings in 1995 until it ended in 2002, attended the bash alongside his wife dressed as a microphone — another nod to his ‘NSYNC era.
Timberlake and Biel were also joined by four male friends who dressed up as the other members of ‘NSYNC. A source tells PEOPLE that the group kept it moving on the dance floor until late into the night.
For the bash, Gerber and Crawford both wore throwback costumes, with Gerber channeling a hippie and Crawford rocking a disco-inspired outfit that included a multicolored sequin jumpsuit and oversized pink glasses. The supermodel, 53, also styled her hair in voluminous curls.
Meanwhile, Rinna dressed up as Jennifer Lopez in her iconic green Versace dress at the 2000 Grammy Awards. The Real Housewives of Beverly Hills star, 56, wore a replica of the dress and showed off long locks styled in a half-up, half-down look similar to Lopez’s.
“To be honest, I don’t really listen,” she said in the clip when asked if she’s a fan of ‘NSYNC. “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.”
“Now you probably know some ‘NSYNC songs, right?” Fallon asked, to which Biel admitted, “Not really.”
