Musician Yoko Ono praised Lady Gaga for her musical talents and her contributions to the world.
"Lady Gaga is in a position of number one as a singer songwriter, in her age, and when you are number one you don't want to risk yourself. And she did. It's incredible and by risking her position she made sure that certain things are corrected in the world, very important things," Ono said. "She is a top singer songwriter in her age, and she has like a 150 million albums sold, at the time that is a difficult age, so it is very difficult to sell you know a hundred thousand, but anyway, she has that power, because of her songs and music are well appreciated by people."
