Lady Gaga recently made a surprise appearance during U2's concert, and played piano on their hit track 'Ordinary love' at the Madison Square Garden.
According to Entertainment Weekly, the 'Bad Romance' singer, who wore black outfit teamed up with a pair of bizarre high heels and a blonde wig, tightly hugged band member Bono before her piano act.
She also sang some of the track's lyrics with other band members.
The news broke when U2 shared their picture with the pop-singer on Instagram with caption "All hail Her Gaganess".
