Britney Spears is on a roll. She’s on a hit TV show, has a huge hit on the radio right now, and now is looking to get back on tour. The megapop star signed with CAA today, thanks to the work of agents Light and Jeffrey Azoff. Brit’s last tour in 2011 did more than well, grossing $37 Million. No word why she left her former agency WME. [AlLindstrom]
