Is Madonna back with her collaborator Mirwais?

Madonna took to Twitter on Tuesday (April 17) to share a clip of herself singing along to a poppy dance track, and one particular hashtag has fans thinking she's reunited with her longtime collaborator Mirwais.

"No This is NOT my new music ------------------ But im having fun in the studio in between takes!! ------------. #music #mirwais #magic," the singer wrote in the caption of the video.

The "Ghosttown" singer confirmed in early 2018 that she has been in the studio working on her 14th record. She's remained cryptic about who she's working with, but by tagging the French record producer and songwriter, many fans are convinced that he's involved. "Is this a hint Mirwais is back in the mix???" one tweeted. "Are you working with #Mirwais again??? Yay!" another wrote.

Madonna and Mirwais previously worked together on three of her albums, including her 2000 record Music, which was nominated for three Grammy Awards and whose title track hit No. 1 on the Billboard Hot 100. They also collaborated for 2003's American Life and Confessions on a Dance Floor in 2005.

Billboard has reached out to Madonna's rep for confirmation that she's reuniting with Mirwais but hasn't heard back as of press time.
