Jill Zarin is still seeking star treatment after leaving “Real Housewives.” Her aides asked restaurants to host her recent birthday dinner for free, requesting a “comp dinner for eight” in return for “press and tweets” about her visit. But there were no takers. Zarin dined Nov. 30 at Lavo with 11 friends, and hubby Bobby paid. Zarin’s assistant, Sarah Vitale, also asked p.r. firms for gifts. But Vitale told us Zarin had no idea: “They sent her stuff in the past, so I didn’t think it was a big deal.” Vitale added that she “reached out to restaurants who have offered to host dinners for Jill in the past . . . we went with Lavo because she’d never been there before.”
