Justin Timberlake unveils Jay-Z song

Justin Timberlake has released a new single with Jay-Z.

Last night the singer-and-actor introduced new track Suit and Tie, which features the rapper and is Justin's first musical offering since his 2006 album FutureSex/LoveSounds.

As well as the song, the 31-year-old posted a letter on his website, explaining the big news a little further.

"This year is an exciting one for me. As you probably have heard through the 'grapevine,' I'm gearing up for a big 2013," he promised his fans.

"Back in June of last year, I quietly started working on what is now, my next journey with that thing I love called MUSIC. The inspiration for this really came out of the blue and to be honest, I didn't expect anything out of it. I just went into the studio and started playing around with some sounds and songs. It was probably the best time I've had in my career… Just creating with no rules and/or end goal in mind and really enjoying the process."

Suit and Tie was co-written and co-produced by Justin and Timbaland, who produced many of the tracks on the singer's last album.

The Friends With Benefits star first aroused rumours of a big announcement by posting a cryptic tweet, followed by a clip on his website, which showed him in the studio.

Justin cheekily addressed the fact he had been keeping his fans in suspense in his letter.

"Some people may criticize me for the last 3 days. But it was fun, right?? Right?!?! Besides, I'd rather speak directly to all of you. And, who can knock me for having a little bit of fun with it?" he wrote.

"Well… No more teasing. Although, it was A LOT of fun. (sic)"

The new single will feature on his album The 20/20 Experience, which is due out later this year.

The crooner let fans in on what they can expect.

"What I came up with is something I couldn't be more excited about! It is full of inspiration that I grew up listening to and some newfound muses that I've discovered along the way," he revealed.
