Everyone is still excited over the reveal of who will be in the cast of Dancing With the Stars season 28 — however, one of the notable faces on the show, Christie Brinkley, admits that her children weren’t exactly head over heels upon hearing the news. The 65-year-old recently attended the DWTS cast reveal at Planet Hollywood and discussed how her kids reacted when she told them that she would be dancing away on stage soon. “They laughed,” the model exclusively told Closer Weekly.
