Justin Timberlake, J.C. Chasez, Joey Fatone, Chris Kirkpatrick and Lance Bass disbanded 11 years ago but rumours of a reunion have sparked a furious response from fans of the 90s boyband in recent weeks.
Justin is said to be planning a special performance with his former bandmates at Sunday's ceremony, where he is being honoured with the Michael Jackson Video Vanguard Award.
The guys appeared to give credence to those rumours when a verified Twitter account for the quintet popped up Saturday.
"Mic check, mic check one.. two...is this thing on?!" read the first tweet from @NSYNC.
The account had more than 51,000 followers at press time.
Justin sparked rumours he was planning to reunite with J.C., Joey, Chris and Lance after the guys were spotted in the VIP section of Justin's recent concert with Jay Z at the Sun Life Stadium in Miami.
Joey attempted to put the rumours to rest when he was spotted arriving to New York this week, insisting he's simply in town visiting family.
"As far as I know I haven't got a phone call or anything, just like his wedding!" he laughed to TMZ, in reference to the band members' suggestions they didn't know Justin was marrying Jessica Biel last year.
Lance meanwhile declined to confirm or deny the reports on his Sirius radio show last week.
"Of course people are automatically going to think we're going to be there performing, but this is exactly how it happened and I knew these rumours were going to fly," he said while addressing the reunion at Justin's Miami concert.
Justin leads the way in this year with six nominations following the success of his latest album The 20/20 Experience.
