He's an elite soccer star, one half of a popular celebrity couple, and one heck of an underwear model. But David Beckham is also a dad and a soccer coach. This summer, Becks is showing his softer side by taking on a new challenge -- Oscar the Grouch. The new Sesame Street season starts on August 11th and Posh's hubby will guest star. He's rumored to go head-to-head with the green, grouchy puppet in what promises to be a hilarious scene.
