Beyonce's seems to be too busy for Clint Eastwood.

The R&B singer was named as part of Eastwood's latest film, a remake of the classic "A Star is Born", since January 2011 but her busy schedule has caused her to back off the project.

"I was looking forward to the production of 'A Star Is Born' and the opportunity to work with Clint Eastwood," Beyonce told E! News on Tuesday. "For months we tried to coordinate our schedules to bring this remake to life but it was just not possible. Hopefully in the future we will get a chance to work together."

With Beyonce gone, the replacement for her role is rumored to be Grammy-winning jazz musician Esperanza Spalding, according to Variety. Spalding won her Grammy for Best New Artist in 2011 by beating top contender Justin Bieber.

There are other big roles that still need to be filled. Many of Hollywood's top male stars are rumored to join the cast including Leonardo DiCaprio, John Hamm, Johnny Depp, and Will Smith. A male lead has yet to sign on and the female role previously held by Beyonce won't be recast until an actor officially joins the cast.

"We've talked to several people, and we probably won't address that one till next year," Eastwood told E! News at the premiere of "Trouble With the Curve".

The musical "A Star is Born" revolves around a star-crossed love affair. Eastwood's version will be the fourth made since the original was produced in 1937 with Janet Gaynor and Fredric March. There was also a 1954 version that starred Judy Garland and James Mason and the latest 1976 remake with Barbra Streisand and Kris Kristofferson.

Beyonce has been busy with her career and personal endeavors with her family. She joined her husband Jay-Z as hosts in New York for a fundraising party for President Obama in September.
