Cher's 'Woman's World' Leaks, Angering Singer

A Michigan club got its hands on Cher's new single "Woman's World" and she isn't pleased about it.

The singer took to Twitter this weekend to share her frustration that a DJ in Michigan leaked an unfinished version of the lead track from her new album -- her first in 11 years.

"I'm upset about the leak," tweeted Cher. "It's not the End of The World, but don't understand how Club in Michigan played min of it? It's not my final mix!"

She went on to explain that her record company pushed the single release date to January to allow more time to finish the track and shoot a video for the song as well.

The still untitled album will feature production work from Timbaland as well as a duet with Lady Gaga according to THR. The singers broke the news of the collaboration earlier this summer, tweeting their excitement about the track.

Gaga told MTV News she wrote the track several years ago, but never put it on one of her albums.

"I always write these concept records, and it just didn't fit in," said Gaga. "Cher heard the song and loved it and wanted to do it together. And I said F--- yeah, it's Cher!"

Cher's last album was 2001's Living Proof. Her greatest hits album "The Very Best of Cher" was realized in 2003, selling over 2.4 million copies according to Billboard.
