Secretary of State Clinton isn't dishing about her daughter's upcoming nuptials. "My lips are sealed," she told NBC's Andrea Mitchell in a Today Show segment this morning. "I am under very strict orders not to talk about it." The rumor mill may suggest a Vera Wang gown and a guest list that includes Oprah and Obama, but the mother of the bride will only say that the event will be very Chelsea. "The people who are coming are her friends and the people who are meaningful in her life," the Secretary of State said. Watch the video of Clinton being mum on Today after the jump!
