It was athlete versus musician at the Andy Roddick Foundation Gala in Austin the other night. John Legend‘s girlfriend, Chrissy Teigen, got into a fierce bidding match during the live auction with Colorado Rockies pitcher Huston Street‘s wife, Lacey, over a visit to the set of “The Office.” Lacey won with a $10,000 bid and Chrissy was consoled by a shout-out from Elton John, who performed at the annual event to benefit children’s charities hosted by tennis ace Andy Roddick.
