Justin Timberlake got back-up from Jay-Z on his most recent album.

Now the 32-year-old crooner is lending his sexy signature voice on the rapper's newest effort Magna Carta... Holy Grail.

But its not just Justin lending a hand, as Beyonce has also collaborated with husband Jay on a different track titled Part II (On The Run) - available to listen on Soundcloud - which is a follow up to their 03 Bonnie & Clyde.

On July 4, Jay-Z's album becomes available for eligible Samsung users who have already downloaded the  #magnacarta app.

The rest of Justin, Jay-Z and Beyonce fans will have to wait until Tuesday, July 9, to buy a copy of the album.

And now that Justin and Jay are best of friends and singing associates, the duo won't mind heading out on tour together this summer. 

Justin no doubt can't thank Jay-Z enough for lending him HIS voice for his lead single Suit & Tie from his hot-selling The 20/20 Experience.

According to Billboard.com, Justin's comeback is the best-selling R&B-hip-hop album so far this year with 2,037,000 copies sold.

Everything the young entertainer touches seems to turn to gold.

Justin, who is married to actress Jessica Biel, is enjoying a successful acting career that seems to be going full steam ahead too.

He recently completed the crime thriller Runner, Runner opposite Ben Affleck and Gemma Arterton.

Justin will soon begin filming the comedy The Last Drop.
