There's a lot going on with Justin Timberlake.

The singer, who successfully resurrected his music career after ditching it for films for a half-decade, will drop his next single from the best-selling 'The 20/20 Experience' in the form of 'Tunnel Vision.' JT co-wrote 'Tunnel Vision' with Jerome 'J-Roc' Harmon, and you can see the sexy single artwork to the left.

The album's current single 'Mirrors' is parked at No. 2 on the Billboard Hot 100. It followed the comeback track 'Suit & Tie.'

And it's been a very good musical year for Timberlake.

Even better news is the fact that JT was featured in a photo on the Kodaklens Instagram page alongside Jay-Z, rapper Nas and Timbaland. These four luminaries were in the studio. Holy amazeballs!

The caption read: "JAY x JT x NAS x TIMBO Rat Pack s---. For some this is "Work"... For us it's just Fun. #RocNation."

You know that's right! Those are four musical luminaries in the same room. That can't be work. Fun for them and fun for us!

JT and Pharrell Williams were also snapped in the studio together. The kid's got some serious musical minds in his corner, and he's no slouch in the talent department himself.

We can't wait to hear the fruits of the labor, er, fun, that are a result of this studio photo.
