New York, September 19 : The nuns who teach at a New York-based school where pop star Lady Gaga once studied were reportedly far from happy when shown a video of her performance.

The nuns at the Convent of the Sacred Heart girls school were shown the video of the singer’s performance at VMA Awards.

The singer, real name Stefani Joanne Angelina Germanotta, is presently known for her scanty costumes and such lyrics as "I wanna take a ride on your disco stick."

"When someone showed the nuns a video of her bloody performance at Sunday night''s VMA Awards, the good sisters were not amused," the New York Post quoted a source as saying.

A spokesman for the school was not available for comment. (ANI)
