Lady Gaga has revealed that she broke down and cried when she discovered Brian May had agreed to appear on on her new album.

The Queen guitarist performs on the track 'You And I', which Lady Gaga has already been including in her live show.

"I fell to the floor crying and laughing when I found out that I'd got him on the song,” she told The Sun. “I called myself Gaga after Queen's track Radio Gaga."

Lady Gaga's new album 'Born This Way' is due to be released on May 23.

As previously reported on Gigwise, the singer made another song, 'Hair', available to download via iTunes yesterday (May 16).
