Desperate Housewives hottie Eva Longoria adamantly dismisses talk that she is dating Oscar winner Jamie Foxx, in whose new music vid she appears and with whom she looked cozy in many post-Golden Globes photos.

Jamie and I are really good friends, and actually he's better friends with Tony [Parker, Longoria's beau]." For the time being, at least.
