Justin Bieber Hangs with "Big Bro" Lil Wayne in Studio

Courtesy: Justin BieberJustin Bieber often calls Usher his big bro, so fans probably didn't bat an eyelash when he tweeted on Wednesday, "Good time in the studio last night. back at it tonight. oh yeah...and big bro came thru."  Except this time, it wasn't Usher he was talking about. 

Justin's tweet included a link to a photo, and the black and white image revealed Justin hanging out and -- apparently -- skateboarding with none other than Lil Wayne.  To stress the point, Justin then tweeted, "and when i say big bro i mean @LilTunechi" -- that's Weezy's Twitter handle.  He also added the hashtags "#BELIEVE IT #family."

It's unclear if Lil Wayne was just visiting, or if he'll actually appear on the Bieb's new album, Believe, which is due out sometime this year.  Justin has been working with Timbaland on new music lately.
