Listen to Justin Timberlake on iHeartRadio

Justin Timberlake fans may have to wait less than they expected to hear the second part of The 20/20 Experience.  

Part Two of the star's recent comeback album was rumored to drop in November, according to collaborator QuestLove of The Roots.  But on Sunday, Timberlake took to Twitter to post a photo of himself in the studio, along with a handwritten sign reading "The 20/20 Experience, 2 of 2, September 30th." 

Justin has remained quiet on the subject of the follow-up, after only briefly confirming to Ryan Seacrest in March. 

When 20/20 dropped that month, it sold 968-thousand copies in its first week.  The album remained at number one on the Billboard 200 for three consecutive weeks.  Its two singles "Suit & Tie" and "Mirrors" are currently in the top 10 on the Hot 100 as well.
