Hudson and her sister open up to Oprah

Perhaps closing a painful life chapter with the May conviction of the man who killed her mother, brother and nephew, singer Jennifer Hudson finally opens up about the tragic events when she sits down with Oprah’s Next Chapter Sunday. Joined by her sister Julia, the Oscar winner tearfully shares her emotional story with host Oprah Winfrey.

They also discuss career, weight loss, impending marriage — fiance David Otunga takes part in the interview, too — and the prospects for a daughter.
