Jessica Biel Dresses as Justin Timberlake for Halloween & He's Her Microphone!

Justin Timberlake and Jessica Biel had one of our favorite Halloween costumes ever!

The 37-year-old actress dressed up as her husband and Justin, 38, was in costume as a microphone while attending the Casamigos Halloween Party on Friday night (October 25) in Beverly Hills, Calif.

Jessica was joined by an entourage of guys who were dressed up as the other members of NSYNC!

The crowd enjoyed signature cocktails including the Casa-delic, Magic Marg and Spicy Spirit, which were served from bars lined with 100s of bottles of Casamigos tequila.
