Olivia Munn is sharing the darkest parts of her cancer journey, revealing how her husband John Mulaney helped her face the "possibility of death." "There's no better person in the world to me than my husband," Munn, 45, said during a Sunday, March 29, appearance on CBS News Sunday Morning. "He is - I mean, you've met him. He wanted to come to every single doctor's appointment." The Newsroom star explained that when she was "faced with the possibility of death and not being here," her husband would lighten the load - both physically and emotionally.
