We previously showed you what it was like in the studio recording As Long As You Love Me, and today we have another!
Check out Justin laying down the vocals (above) on our FAVORITE song off the album, Beauty And A Beat!!
The completed version has Nicki Minaj on it and was produced by Max Martin!
Want to see even MORE of Justin behind the scenes??? Get to your nearest Target store and purchase the deluxe edition of Believe, which includes a DVD with bonus footage!
You can also tune into NBC tonight at 8pm for night one of JB's All Around The World concert special!
