Singer Michael Buble has a secret acting past - he once appeared on an episode of The X-FILES.
The Canadian crooner admits he jumped at the chance to earn a little cash when he was asked to play a sea-faring extra.
He tells Parade magazine, "It was a very small part. I was a sailor. I just needed the money. My singing career was non-existent at that point."
And he didn't have to dig too deep to find his sea legs - before his music career took off, Buble used to take to the sea with his fisherman father off the coast of Vancouver, British Columbia.
