People.com Celebrity Leonardo DiCaprio's Grandmother Dies Helene Indenbirken, whom the star called Oma, was 93 and had been in ill health By Karen Nickel Anhalt Published on August 6, 2008 08:50 AM Share Tweet Pin Email Photo: INF Leonardo DiCaprio is mourning the death of his beloved maternal grandmother, Helene Indenbirken. Indenbirken, whom The Departed star called Oma, was 93 and passed away in a hospital in her native North Rhine-Westphalia, Germany, according to Indenbirken’s hometown paper, the Recklinghauser Zeitung. No exact date or cause of death has been reported. Only last week, DiCaprio and his mother visited Indenbirken in the hospital in Oer-Erkenschwick. Her health apparently had begun to decline earlier this year. As her grandson, 33, who often took Indenbirken with him to his premieres and on to his movie sets, once told Vanity Fair: “She is literally gangsta, and I mean that with an ‘a.’ She will tell people exactly what she thinks to their face and look them in the eye.” DiCaprio is due back in Oer-Erkenschwick, to attend a small memorial service.
