Justin Timberlake is bringing sexy back (again)  and his wife is his biggest fan!

JT took the stage at the Brit Awards in London on February 20, and wife Jessica Biel loved every second of it.

Following Justin's performance, Jessica tweeted:

At the awards show, Justin gave a live performance of his new song "Mirrors" for the first time ever. 

Justin performed the song while decked out in a Tom Ford suit and tie, according to MTV.

But these days, would we expect Justin in anything but a suit and tie? We think not.
