Conan O'Brien and George Lopez are expected to make a splash in their first week together in November on TBS with a lineup of A-list guests. I've heard that Sandra Bullock, who is George's close friend and executive produced his ABC sitcom, may appear on his newly moved 12 AM-1 AM talk show that week.
