KELLY Bensimon really is sorry for being obnoxious to Bethenny Frankel on “The Real Housewives of New York City,” despite claiming otherwise on the show. The women got into a spat after Frankel sniffed that haughty Bensimon thought she was Madonna. Bensimon then called a one-on-one meeting and told Frankel, as she moved her hand from table height to above her shoulder, “You’re down here, and I’m up here.” But Bensimon later sent Frankel an e-mail: “I honestly owe you an apology.” Bensimon lists several mitigating factors: 1) an ex-boyfriend “harassing me like crazy,” 2) “I was late because I had to organize the girls to go to the beach,” and, 3) “My driver who has been with me since I was 23 told me he had terminal cancer.” The former model concludes, “I am horrified that I was rude to you.” If only Kelly had said that on air, viewers wouldn’t hate her so much.
