Rebel Wilson talks overcoming health struggles, writing her 'truth'

Rebel Wilson opens up to Hoda Kotb and Jenna Bush Hager about her deeply personal and honest memoir "Rebel Rising," and how she went "against the grain" when writing it. "When you write your truth not everbody is going to be happy with it," she says. "I've often gone against the grain and done what people said not to do, but at the end of the day I'm authentic to myself." She also opens up about her engagement and 17-month-old baby.
