Jessica Biel [1] wasn't an *NSYNC fan growing up [2], but that didn't stop her from absolutely slaying a '90s-era boy band costume at the Casamigos Halloween [3] party on Friday night. Yep, the 37-year-old Limetown [4] actress dressed up as her husband, Justin Timberlake [5], for the star-studded bash, and she really nailed every detail — even the ramen hair.

Jessica channeled Justin's 1999 American Music Awards outfit [6] for the event, and he was her perfect partner in a giant microphone costume. To top it all off, they were accompanied by four friends who acted as the remaining *NSYNC members. Jessica recently admitted her lack of boy band knowledge to Jimmy Fallon [7] on The Tonight Show [8]. Turns out, she doesn't need to know Justin's songs by heart to iconically channel his '90s vibes!
