Diddy put on his Executive Producer hat for the high school football based documentary Undefeated. And the movie just won the Oscar! At tonight's 84th Annual Academy Awards, Sean "Diddy" Combs' emotional film Undefeated just won for Best Documentary. Although he didn't get on stage with the other 5 members of the production/film team to accept the award, he walked the red carpet earlier. And was spotted in the audience sitting directly behind his rumored boo Cameron Diaz.
