Superstar Barbra Streisand has turned down a massive $100 million offer to take up a residency in Las Vegas, according to reports.

The Woman In Love singer, 67, has allegedly been approached to follow in the footsteps of Cher, Celine Dion and Bette Midler by signing a three-year contract with a Sin City promoter.

A source tells PopEater.com, "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.

"She's an international star and the only performer in the world that would make people flock to Vegas year after year."

But the veteran entertainer is not interested in the bumper pay cheque and has rejected the deal in favour of a summer 2010 tour.

The insider adds, "Money has never been a deciding factor in her career. She plans on touring again this summer instead."

Streisand proved her superstar status in October when she stunned music experts by storming to the top of the U.S. album charts with her 63rd release, Love Is the Answer, beating Paramore and Mariah Carey to the coveted spot.
