On the May 19 episode of “The Ellen DeGeneres Show,” Sia uniquely recreated her buzzworthy music video for “Chandelier.”

In DeGeneres’ introduction of the performance, she said that Sia had “written No. 1 hits for artists like Madonna, Rihanna and Beyonce…” That made us pause, considering Madonna has not yet released a tune written by Sia (though the other divas have).

Could that mean Sia might be at work on Madonna’s upcoming album? Maybe DeGeneres inadvertently disclosed some new information? After all, Madonna has been busy sharing Instagram photos of a number of collaborators over the past month or so (like: Diplo, Toby Gad, Natalia Kills, Martin Kierszenbaum, S1, MoZella, Ariel Rechtshaid and Nick Rowe).

Sia’s publicist says that Sia has not written for Madonna, nor is she writing for an upcoming project. Thus, it was a slight error on DeGeneres’ part.

(Still, we’d like to think DeGeneres was perhaps projecting her desire for a possible Madonna/Sia collaboration.)

There is no word on when Madonna’s next album might be released, but, Sia’s new set, “1000 Forms of Fear,” is due out on July 8. “Chandelier” debuted on the Billboard Hot 100 a week ago (chart dated May 31) at No. 75. It’s bubbling under the threshold of the Pop Songs airplay chart.
