Looks like Paris Hilton only has eyes -- this week -- for Nicole Richie's baby daddy's brother, Benji Madden.
After being spotted together over the weekend in St. Louis, Paris and the Good Charlotte member (who recently called off his engagement to Australian singer/model Sophie Monk) were on the same flight back to LAX -- but deplaned separately on Sunday. No word if Mile High Club officials were called to the scene.
Paris & Benji Get High Together
