Desperate Housewives star Eva Longoria was so desperate to get hold of a TV presenter's bow-tie at the Golden Globe Awards Monday night, she offered to buy it from him. Former Saved By The Bell star Mario Lopez was making his debut as a presenter for news show Extra when Longoria challenged him about his smart bow-tie. She told the stunned TV star, "I like your tie. I'll buy it, but I want it now." But Lopez had already agreed to donate his tie to the Clothes Off Our Back charity auction, and insisted the actress would have to bid for it like everyone else.
