New Delhi, Apr 14 : If Britney Spears’ back-up career plan includes being a geography teacher then she should strike off that option, especially after her “Sacramento in San Jose” blunder.

On April 11, 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, which is around 90 miles from San Jose, the previous night as her ''The Circus Starring Britney Spears'' tour makes its way across California.

The comeback queen’s address to the crowd came in the second portion of her set between songs ''Me Against The Music'' and ballad ''Everytime'', reports The China Daily.

This is not the first time her tour has made controversial headlines. The singer suffered a ''wardrobe malfunction'' at a show in Tampa, Florida and told the mainly teenage crowd that her: "P***y was hanging out."

While in Vancouver, Britney left the stage for 25 minutes reportedly because it was too smoky.

She later told the crowd: "Thanks Vancouver. You were wonderful. Drive safe. Don''t smoke weed!" (ANI)
