Tom Brady needed fashion advice from Gisele Bundchen over Oscars weekend. Bundchen co-hosted an after-party for Mario Testino’s Prism Gallery show at mega-mansion Fleur de Lys, where the NFL jock asked his top-model spouse about his look. “He was wearing a goofy gray cardigan,” said a spy. “And he asked Gisele as they left, ‘Was this OK?’ ” No wonder Brady was intimidated: Guests included decked-out Naomi Campbell, Karolina Kurkova, Miley Cyrus, Alessandra Ambrosio, Stavros Niarchos and Jessica Hart, Zac Posen and Vogue’s Hamish Bowles. The bash was so hot, we hear crashers tried to sneak in through the bushes, “to no avail.”
