Adding more excitement to the boy band reunion, they came out with an official Twitter account on Saturday, Aug. 24.

"Mic check, mic check one.. two... is this thing on?!" the first tweet simply read. (The group's last television performance was during a Grammy Awards tribute to the Bee Gees in 2003.)

NSYNC "will reenact some of their greatest videos in a medley," a source told Us Weekly of the reunion. "Then Justin will sing his new song 'Take Back the Night' and get his [Michael Jackson Video Vanguard Award]."

On Saturday, Aug. 24, Timberlake also shared a part of his performance outfit via Instagram within the same hour of the Twitter surprise. "Counting down to the VMAs," he captioned with a picture of his white and silver shoes.

The MTV Video Music Awards air live on Sunday, Aug. 25, at 9 p.m. EST.
