Doctor Who star John Simm is recovering from a shocking family discovery.
While appearing on the U.K. series DNA Journey, the British actor, 54, learned that his late father Ronald Simm was not his biological parent following a genetic test that showed it was actually a man named Terry Smith, according to U.K. newspaper The Telegraph.
“It spun my world, and everything I thought I knew, wasn’t real,” said Simm about the discovery in a statement sent to PEOPLE. “It’s turned out to be such a massive thing in my life.”
The Yorkshire-born actor joined the series with his Life on Mars costar Philip Glenister to delve deeply into their ancestral background — though he could never have predicted the revelation he would come across.
