Robert De Niro has split from his wife of over 20 years, Grace Hightower, according to Page Six. De Niro and Hightower married in 1997 after dating for nearly a decade, and they have two kids together. A source said to be close to the couple claimed that they are no longer living together and the couple will reportedly announce their split in the coming weeks. One unnamed source told Page Six: “De Niro and Grace are breaking up. He’s been at a few things since the very end of the summer without her—and rumor has it they are done.” De Niro filed for divorce in 1999 but the couple worked out their differences and renewed their vows in 2004.
