Lady Gaga Plays John Lennon's Piano; Fans Attack

Maybe Lady Gaga should rethink calling fans little monsters — her haters are taking the title a little too seriously. Gaga has stirred up some trouble on Twitter once again as fans attack her for playing John Lennon's piano.

John's son Sean Lennon posted a picture (via MTV News) of Lady Gaga on his Twitter playing the white piano with the caption, "With gaga at mom's house, she's belting on the white piano."

The pic was quickly taken down when fans started to complain that Lady Gaga shouldn't have been allowed to touch the piano, but Sean Tweeted back his reasoning.

"Pianos are meant to be played," he Tweeted. "Why is everyone so uptight? What should we do, lock it away in a dusty room? So judgmental."

"Firstly, he gave that piano to my mother for her birthday, it is hers, secondly, he was not uptight the way you seem to be," Sean Tweeted back to a fan.

But then he let the argument go.

"Come on, lighten up ... life's too short, there're enough real problems in the world."

Good point!
