On the Dance/Club Play Songs chart to be released on Billboard.com Thursday (Jan. 20), "You Haven't Seen the Last of Me," the song of the U.S pop-singer of Armenian origin, Cher, reached No. 1, making the leading lady the only act to have notched a No. 1 single on a Billboard chart in each of the last six decades.

In fitting Cher style, she tells Billboard, "How can it be six decades when I'm only four decades?"

"You Haven't Seen the Last of Me" is lifted from Cher's film "Burlesque" and won a Golden Globe Award for best original song Sunday (16). Written by Diane Warren, the ballad was remixed into an uptempo number for dance floors by the likes of Dave Aude, StoneBridge, Edson Pride and Almighty.
