I love Bravo for “Top Chef” and “Project Runway,” but I’d rather watch TV than be on it. If you want to be the next reality star, here’s your chance: Casting directors from Bravo are holding a casting call for a show called “Make Me a Supermodel” (based on UK series) — they’ll be in town Sept. 14 and 15, but the location hasn’t been announced yet. Check Bravo’s site for updates.
