Lady Gaga debuted a new song during a performance in Minnesota last night (August 30).

The singer introduced the piano-led ballad to fans at the Xcel Energy Centre in Saint Paul as 'Living On the Radio'.

It is not known if the song is a new single, or whether it will feature on Lady Gaga's as-yet-untitled follow-up to her debut 'The Fame'.

A video has been posted on YouTube by user IAmFree1974 - and can be watched below now.

The singer has previously stated that the album is due to be released in the New Year.

Lady Gaga is currently on the North American leg of her Monster Ball world tour, and is due to play in Saint Paul again tonight (August 31).
