KATIE Price said she was shocked to discover her son Harvey’s incredible piano-playing skills ahead of his performance at a charity event called Autism’s Got Talent.

In the final episode of her Quest Red reality show, Katie Price: My Crazy Life! Harvey, 17, unleashes his inner rock star while playing with his piano teacher, Adam.

“Harvey’s always played the keyboard, but I don’t quite know what he’s capable of,” said the former glamour model, who lives near Horsham.

Despite Harvey never having heard the tune before, he improvise his own piece, keeping time and staying in key with his teacher.

"How can he make that up? That fascinates me," Katie, 41, asks.

Adam explains:"For Harvey, music is his words. Music’s his language. He’s what we call a savant, a wise person."

Harvey has played the keyboard since he was four old and couldn’t talk.
