Miley Cyrus is filling two hours of primetime on NBC tonight. 

The network is airing a two-hour documentary special about the controversial pop star and her equally controversial "Bangerz" world tour that swept through North America earlier this year.   



The special will follow Miley behind-the-scenes and on stage at her recent stops in Barcelona and Lisbon.  

The network says the documentary aims to "examine what makes [Miley] such a global phenomenon."   

"Miley Cyrus: Bangerz Tour" is set to air at 9 p.m. Eastern on NBC tonight.
