Pictures of Britney Spears Performing a Mini-Concert on Jimmy Kimmel Live

Britney Spears hit the stage in a parking lot packed with screaming fans at Jimmy Kimmel Live's studios in LA last night. Yesterday marked the release of her seventh studio album, Femme Fatale, and she celebrated with two appearances. Brit began the day by airing Sunday's SF performances on Good Morning America and ended with a port-a-potty prank and her now-standard three-song repertoire on Kimmel. Jason Trawick and her manager, Larry Rudolph, were waiting in the wings with Jimmy while Brit modeled new glittery bodysuits and belted out "Hold It Against Me," "Big Fat Bass," and "Till the World Ends," one of which is among BuzzSugar's top picks from her record. Brit's latest miniconcert gave us a taste of what she'll pull out this Summer on her North American tour, but there is still no word on who will replace her former traveling mate Enrique Iglesias.
