Get ready for the 'N Sync reunion.
And not just any reunion—they will be performing a medley together on Sunday at the MTV Video Music Awards.
"It's a matter of songs now," a source says.
As E! News first reported earlier today, the guys were deciding between performing one song, a medley or keeping it to a non-musical appearance.
'N Sync last performed during a televised tribute to the Bee Gees at the Grammys in 2003.
The boy band reunion rumors popped up earlier this week when the New York Post claimed the guys would reunite for a performance when Timberlake receives the Michael Jackson Vanguard Award during the big show at Brooklyn's Barclays Center.
MTV reportedly approached Timberlake about a reunion because producers felt it was only right to acknowledge the group as part of the honor.
Fatone's father reportedly told Radar Online earlier today that the night will include a performance.
Jimmy Fallon will present Timberlake with the award.
