Lady Gaga tickles John Lennon's ivories. Beatle fans scream blasphemy!

gaga-lennon-piano.jpgBeatles fans are reportedly quite irate about Sean Ono Lennon daring to let Lady Gaga play his father John Lennon's white piano, a gift he gave to Yoko Ono in the early '70s.

Sean recently tweeted a photo of the fishnet-clad Gaga seated at the white grand piano. But after a Twitterfire of criticism, he removed the picture of his musical friend. The gist of the Beatle fans' ire was that Gaga wasn't worthy to play the holy relic.
