• Jessica Biel won Friday night's round of Halloween costumes, dressing as Justin Timberlake in *NSYNC.
  • She even did the curly hair!!

Regardless of how you feel about couple's costumes, trolling your partner by dressing up as them for Halloween is pretty good—especially when your partner happens to have been a member of an iconic boyband!

For the first night of the first Halloweekend this year, Jessica Biel decided to go for the gold (aka the title "Best Halloween Costume of 2019") by dressing up as her husband Justin Timberlake. But not Sexy Back Justin or Man of the Woods Justin—oh no—Jessica decided to dress up as *NSYNC Justin at the Casamigos Halloween party this year, and it's pretty amazing:

Please note the blonde wig, which is just *chef's kiss.* I'm also choosing to believe that Jessica borrowed the tiny sunglasses and bedazzled cross necklace from a box that Justin keeps in their basement labeled "*NSYNC things I couldn't say bye bye bye to." And if you're wondering what Justin went as, well, he went as a microphone, which is WAY less exciting:

What makes this costume even funnier is that Jessica wasn't an *NSYNC fan back in the day. When Jessica appeared on The Tonight Show recently, Jimmy Fallon played an old clip of her saying that she wasn't too into the band. "To be honest, I don’t really listen,” she said. “I mean, I know of them, of course. And I’ve heard of them, and I’ve heard the music. But I don’t think I own any of their CDs. I’m not a huge fan. But, cool, I guess.”

How times have changed!
