Britney Spears is preparing to launch a new $100 million comeback world tour.

The troubled pop star is already said to be in training to hit the road again, as she concludes talks for the new shows, in order to avoid the embarrassing performances such as her appearance to the MTV VMA ceremony last September.

A somewhat optimistic source reveals to the News Of The World, “There will be no more on-stage blunders. Britney's turned a corner and the world will be amazed with her.

“Things are looking up for Britney. She's finally focusing on her career again."
