Sting's Wife Wins After Betting on Giacomo .c The Associated Press NEW YORK (AP) - Wouldn't you bet on a horse named after your son? When Giacomo, the 50-1 long shot named after Sting's 9-year-old son, won the Kentucky Derby May 7, the singer didn't have any money down - but his wife did. Trudie Styler, who is married to Sting and has four children with him, turned $500 into $25,000 by betting on the horse. Giacomo is owned by Jerry Moss, the co-founder of A&M Records, which signed Sting's old band, the Police, in 1978. ``On the day of the race, we were backstage in New Hampshire and my wife called and said, `You'd better watch the television because our son is racing,''' Sting told Rolling Stone magazine in its latest issue. ``Then she said, `I'm gonna put some money on it.''' As for the winnings, Sting says it might already be gone. ``It's my wife's money,'' he says. ``And she's probably spent it already.'' Giacomo will race Saturday at the Preakness, the second leg of racing's Triple Crown. He sits with significantly better odds at 6-1. On the Net: http://www.rollingstone.com
