The 27-year-old singer left the crowd at her show in San Jose, California, confused after greeting them with the words: “What’s up Sacramento?” 40 minutes into her set. Britney had performed in Sacramento – approximately 90 miles from San Jose – the previous night as her ‘The Circus Starring Britney Spears’ tour makes its way across California.

Britney’s address to the crowd, her first words of the night, came in the second portion of her set between songs ‘Me Against The Music’ and ballad ‘Everytime’. Britney’s tour has previously proved controversial with the singer suffering a ‘wardrobe malfunction’ at a show in Tampa, Florida and telling the mainly teenage crowd that her: “P***y was hanging out.”

Britney also left the stage for 25 minutes at a recent show in Vancouver, Canada reportedly because it was too smoky. She later told the crowd: “Thanks Vancouver. You were wonderful. Drive safe. Don’t smoke weed!” Reports said lighting technicians at the concert couldn’t breathe properly because fans were smoking cigarettes and marijuana – a drug also known as weed.

Meanwhile it has rumoured Britney has been getting close to her ex-husband Kevin Federline, who is traveling alongside her with the couple’s two sons Sean Preston, three and Jayden James, two. A source said: “It’s like they’re newlyweds all over again. Britney and Kevin can’t keep their hands off each other.”
