Lady Gaga has unveiled her latest collaboration with Tony Bennett, titled Nature Boy.

The song is taken from the duo's joint album, Cheek To Cheek, which is due for release on September 22.

Jazz standard Nature Boy was written by Eden Ahbez in 1947, with the likes of Nat King Cole and Miles Davis.

"You will recognize it also famously as used in 'Moulin Rouge,' but our rendition with the now late multi-reedist Paul Horn is spectacular.

"Horn was meant to join Tony & me for the PBS special but sadly passed just weeks before, a New Age Jazz pioneer, lets celebrate him 2day.

"You will hear his genius in the flute solo of our "NATURE BOY" a solo that will echo through the world today. And forever. #TheGreatPaulHorn."

[related]She added: "It wasn't until 1947 that the song was published, written sometime during/after 1941 while pianist Ahbez wandered LA eating only raw fruits.

"It's just so interesting. This composer was part of a sub-culture of nomadic hippies! We channelled our own Gypsy lives in this performance."

As well as premiering Nature Boy, the pair also recently unveiled the music video for I Can't Give You Anything But Love.
