Call them Friends with benefits. You already know that when Jennifer Aniston guests on the March 27 season finale of Courteney Cox's FX drama Dirt, she'll be playing her bosom buddy's archenemy, a rival tabloid editor. But what I've learned - muahaha, exclusively! - is that Aniston's character is a lesbian. What's more, she won't just mouth off to Cox's tightly wound counterpart, she's going to share a liplock with her. An FX rep declined to comment, but Joey Tribbiani had this to say: "Yeah, baby!"
