Charlize Theron spent the weekend admiring the heavyweights at the UFC slugfest in Las Vegas. The actress, her producing partner Beth Kono and a few other pals sat front-row at the MGM on Saturday night — guests of UFC president Dana White and CEO Lorenzo Fertitta. Theron revealed last year to Vogue that she has a “new affection” for the UFC. The star later jetted to New York to continue her press tour for her new movie “Snow White and the Huntsman.”
