Britney Spears has been derided for many things in recent years - her lifestyle, image, music, lip syncing and dancing amongst others - but last night she proved her doubters wrong on the first night of her new tour in Sacramento, California, reports Rolling Stone. Britney Spears, who has been the target of anonymous online abuse about failing to sing live and poor dance routines in recent months, had her mic turned on and rattled through a series of glitzy costumes and fast-paced dance routines, and performed hits such as 'Toxic' and 'I'm a Slave 4 U'. Rolling Stone also praised opening act NICKY MINAJ, but claimed: ".the night belonged to Britney: She managed to prove that she's still progressing as a showgirl. Not only that, she's doing it better than even diehard defenders would've predicted."

Britney's tour began a day after ex-boyfriend Justin Timberlake had leaped to her defence when asked about the amount of anti-Britney feeling on the internet, PopCrush reported, commenting: "People think they can say anything and it doesn't matter to people. I'd love to see the people who comment about Britney online say those things to her face, because they couldn't", when asked about her dancing he said: "In Britney's defense, if you pulled up a video I did from 2003, I couldn't do the sh*t I did then either." The New York Daily News reported that Britney had tweeted a photo of her and boyfriend Jason Trawick hugging each other just before she went on stage for her first night of the tour. "Sacramento was on fire tonight," she tweeted after the show. "You ready San Jose? Cause I am!!!!"
