Bookies are cashing in on Amy Winehouse’s stealth pre-show disappearing acts by taking bets on whether or not she shows up to her next gig. The gambling began when Winehouse cried exhaustion last weekend after soundcheck at T in the Park, but then headed to — no shocker — a pub. Her beehiveness was photographed boozing throughout the evening while crowds were turned away at the gate. So far bookie William Hill is offering half odds that Winehouse plays hooky for her Eden Project performance in Cornwall next Tuesday. In the past, the gambling market has gotten in on predicting band reunions and whether or not Madonna would wind up in the slammer.
