After an off-and-on, 21-year-long relationship and two children together, the iconic actor Robert De Niro and his wife Grace Hightower announced in November that they’d be splitting for good. De Niro has always kept his personal life out of the spotlight as much as possible, meaning that some fans were unaware that he was even married.

The De Niro-Hightower union wasn’t always a smooth ride, with at least one separation and custody battle over the years before the couple renewed their vows in 2004. After revealing the news of their divorce, De Niro issued a statement saying, “I honor Grace as a wonderful mother and ask for privacy and respect from all as we proceed to develop our roles as partners in parenting.”
