The teen sensation hit the ramp with the Young Money chief in between recording his upcoming album Believe.
“Good time in the studio last night,” tweeted the Biebs.
“Back at it tonight. oh yeah…and big bro came thru.”
Last night in the studio with TImbaland good times. back at it again tonight. Big Bro Lil Wayne stopped thru. #BELIEVE IT. all family.
While he didn’t say if he and Weezy had collaborated, Timbaland has been in the studio with the pop idol.
“yo @justinbieber played me some of his joints last nite, craziee. the dude is super talented & our work ethics are just alike. #hitsondeck,” tweeted Timbo.
And for those wondering how it all went in the studio, Bieber's longtime manager, Scooter Braun, filled fans in. "got great reports on the first night with @justinbieber and@timbaland," Braun tweeted.
"Exciting stuff. heard stopped by too. gonna be interesting."
Drake and Kanye West are also among the contributors to Bieber’s sophomore album, due later this year.
