A 30 second snippet of Lady Gaga's duet with Florence Welch – 'Hey Girl' - has surfaced online, NME reports.

The clip will feature on Gaga's forthcoming new album, 'Joanne', which is out on October 21.

Of the track the singer recently said: “Me and Florence did a duet together. I started to work on an idea for a song that I really wanted to do with a girl and you'll see why when you hear the music what the song is about. She's really to me, if not the best but one of the greatest vocalists in the world. She's incredible. I would say the same about the musicianship of Beck, of Father John (Misty), Kevin Parker and Mark Ronson."

A series of other snippets from the record have also emerged including the title track, 'Come To Mama' and 'Diamond Heart'.

Earlier, Gaga also released new single 'Million Reasons', which she also played as part of her recent intimate tour of 'dive bars'.

Performing in Nashville, she opened with the consecutive new tracks 'Sinner’s Prayer' and 'A-Yo', before inviting country singer-songwriter Hillary Lindsey onstage to debut the Bowie-inspired 'Million Reasons', which the duo co-wrote. She ended the show with recent single 'Perfect Illusion'.

Gaga's fifth studio effort will feature 11 tracks on its standard edition and 14 on the deluxe version.
