Brad Pitt's publicist is denying an US Weekly cover story that claims to have "proof" that Jennifer Aniston's soon-to-be-ex is romancing Angelina Jolie. In the article, US quotes employees of a California hotel who claim they saw the pair — costars in the upcoming film Mr. and Mrs. Smith — being affectionate. "This particular story," Pitt's rep says, "is completely untrue." Pitt's rep is also denying reports that the Earth is round and those white puffy things in the sky are clouds.
