Christina Grimmie's Mother Dies After 'Brave' Battle With Breast Cancer

"She will be missed immensely," the family said in a statement.

Tina Grimmie, the mother of late singer Christina Grimmie, has died of breast cancer

"We are saddened to announce the loss of our beloved Tina, also affectionately known as 'Mama Grimmie' to the millions of fans of Christina Grimmie around the world," the Grimmie family said in a statement Sunday. "She will be missed immensely."

The statement continued: "Tina fought a courageous and brave battle with cancer for many years, even until her final hours with family by her side. While this is a bittersweet moment for us as a family, particularly after losing Christina two years ago, we rejoice at the thought that Tina and Christina are united once again in the presence of our Lord and Savior."

Christina Grimmie was 22 years old when she was shot and killed while signing autographs for fans during a meet-and-greet following an Orlando concert on June 10, 2016.

After the singer's death, her family launched a foundation in her name to support families fighting breast cancer and suffering from the effects of gun violence.

Instead of flowers, the family asks that well-wishers make donations to the foundation in Tina's honor.
