Jamie Lee Curtis tearfully revealed that she became a grandmother less than one week after her friends Rob Reiner and Michele Singer Reiner died. "The truth is that the greatest lessons [and] the hardest days ever in my life have been being a parent, and now a grandparent," Curtis, 67, said during the Wednesday, April 1, episode of Michelle Obama and Craig Robinson's "IMO" podcast. "My husband and I became grandparents to our eldest daughter and her husband." Curtis and her husband, Christopher Guest, are parents of daughters Annie, 39, and Ruby, 30.
