"After Celine Dion left Vegas, no one has been able to replace her. Bette Midler failed, Cher is trying, only Barbra is guaranteed to succeed," the Daily Express quoted a source as telling PopEater.com. "She's an international star and the only performer in the world that would make people flock to Vegas year after year," the source added.
But the Woman In Love hitmaker was said to be not interested in the massive pay cheque. The insider added: "Money has never been a deciding factor in her career. She plans on touring again this summer instead."
