Helena Christensen is a proud mum - her seven-year-old son is a chess prodigy. The supermodel insists Mingus excels in the board game and has even been asked to play on the American national team. She says, "We've just discovered he's a great chess player. He went to his first tournament and came third out of 50 children and was asked to play on the American national team. He's only played for two years. He already beats (his dad) Norman Reedus."
