Listen: Lady Gaga feat. Florence Welch - 'Hey Girl'.

Today’s the day, Lady Gaga’s new album 'Joanne' is out, featuring assists from a star-studded line-up including the likes of Florence Welch, Kevin Parker, Josh Homme, Beck, Father John Misty, Este Haim, Elton John, Bloodpop, and Mark Ronson on co-Executive Producer duties with Gaga herself.

Earlier this year during an interview with BBC Radio 1, Gaga said about her collaboration with Florence: "I started to work on an idea for a song that I really wanted to do with a girl. You'll see why when you see what the song is about. I just thought, 'Who do I want to sing with?' [Florence]'s really to me if not the best, one of the greatest vocalists in the world. She's incredible."

P.S. 'Million Reasons' is really, really good. I highly recommend.
