QB Tom Brady looked as sharp as ever at this year’s Kentucky Derby. He was there - reportedly wearing Tom Ford - with his Pats pal Wes Welker, and celebs such as Ashton Kutcher, “Twilight’’ actor Kellan Lutz, and singer Miranda Lambert. The fast-traveling Brady was in New York by Saturday night so that he could join his wife, Gisele Bundchen, at celebrity hair stylist Harry Josh’s Hairball party at the Standard Hotel. We assume the couple will turn up again at Monday’s Met Ball. . . . Other Boston faces at Derby festivities included Sweet Cheeks chef Tiffani Faison, who served up a dish featuring her beloved biscuits at a “Taste of Derby’’ gala on Thursday night. Faison attended Saturday’s big race with her wife, Kelly Walsh.
