Iggy Azalea, the "Fancy" rapper from Australia whose star-making year recently culminated in four Grammy nominations, will headline Royal Farms Arena on May 13. Nick Jonas, Tinashe and DJ Whizz Kidd will also perform as a part of Azalea's North American Great Escape Tour. Tickets go on sale to the public at 9 a.m. Friday on AEGLive.com. Azalea remained a presence on the charts this year thanks to hook-oriented singles from her debut album, "The New Classic," such as "Problem," featuring Ariana Grande, and "Black Widow," featuring Rita Ora. The Grammys will air on CBS on Feb. 8.
