Paunchy Jack Osbourne, Ozzy's 19-year-old son, has made quick work of his kick-boxing debut in Thailand.
Osbourne had four weeks to prepare in a muaythai kickbox camp, a tough regime that included coffee enemas. He said he was "mentally and physically prepared."
Parents Ozzy And Sharon flew to Pattaya to cheer him on.
Jack said, "Mum and Dad were cool about it."
