MARC JACOBS is still gay, but he's not with JASON PRESTON anymore. Preston, you'll recall, is the comely lad who's dabbled in escort work and who looks eerily similar to the co-star of Barebackin' Boyfriends 2. Just recently, he gave HX an interview gushing about Jacobs, the glamorous life they lead, and their distaste for other gays. But Jacobs tells Pride magazine that their relationship is now more over than pashmina shawls. "I wanted things to be a certain way, and it's just not working," he said, sadly. "I wanted him to be there when I wanted him to be there. I have to be in bed at 11:30 and he's 25 and wants to go to clubs every night. . . . I adore him. But do I want to control him? No." Besides, said Jacobs, the fling was affecting his work ethic ("My head was somewhere else"). Whether it affected his image and his relationship with his backers I'll never know. (My friends actually think it helped.) In any case, Preston should probably now consult JOHNNY "Wino Forever" DEPP about how to rewrite a huge tattoo of your ex-lover's name.
