The duo made the lo-fi recording on the same day Allen appeared as a guest on ‘The Ellen DeGeneres Show’ earlier this week (February 18). She is seen sitting next to DeGeneres in a bathroom before launching into the song.
DeGeneres, who joins Allen by singing vocals on the cover, has previously been joined in similar circumstances by Pink as part of what she is billing as the ‘Bathroom Concert Series’.
As you’ll see from the ‘Womanizer’ video clip below, Allen and DeGeneres‘ ad-hoc cover isn’t completely successful – the two burst into laughter halfway through and are unable to finish the song because they forget the words.
Allen has recorded a version of the song before, and also performed it as an encore at her recent London gig.
