Veteran singer Sir Tom Jones turned heads in a London park when he stripped off to sunbathe in a pair of skimpy shorts.

The 73-year-old crooner was photographed soaking up the sun in London's Victoria Embankment Gardens wearing nothing but black trunks and a pair of sneakers.

Jones was seen sprawled in a deckchair in the public park.

An onlooker tells Britain's Daily Mail, "I couldn't believe it at first. I did a double take and realised it was Tom Jones. He didn't seem to care who saw him, he was just relaxing with a friend. He looked like one of the crowd."
