Lady Gaga‘s bizarre costumes and lavish sets broke the bank during her 2009 Monster Ball Tour. “I actually went bankrupt . . . and it was funny because I didn’t even know,” the chart-topping pop diva claims. The 200-show tour grossed about $125 million, but the wildly staged concerts cost more than that to produce, and landed her $3 million in debt, Gaga told the Financial Times. Still, she claims she doesn’t care about money: “The only big things I’ve purchased are my dad’s heart valve and a Rolls-Royce for my parents, for their anniversary.”
