It's safe to say Britney is back, singing live, dancing her butt off, and putting on a kick @$$ show! Britney debuted her Femme Fatale tour in Sacramento, California last night with special guest Nicki Minaj and she did not disappoint. For most artists, the first show has a few bumps in the road, but from what we've seen, it looks like Britney gave it her all, sang live, and put on possibly one of the best 'performances' she's done in quite some time. We heard how excited she was to get back on stage, and perform to sold out arena's around the world, but we couldn't help but be concerned that our Brit Brit might not be ready. By seeing the video's after the jump, you can see why all our hesitation left as we watched a radient Britney Spears perform all her biggest hits (and some new songs from Femme Fatale) without any hesitation. We can only imagine that the show will only get better with time. I'm SO excited for Britney to get back to what she loves doing (and honestly genuinely giving it her all) with these high energy, amazing vocals, awesome costumes and props, and excited fans all over the world!
