She was 43.

Grinstead’s sister and fellow 702 group member, LeMisha Grinstead, wrote on Instagram: "It is with great sadness that I have to let you know that my beautiful sister and friend has passed away this evening."

She said: "She has had a long battle and she is finally at peace. That girl was as bright as the stars! She was not only beautiful on the outside, but also within. Sharing the stage with her was a joy I will cherish for the rest of my life! We, the family ask for prayers and respect for our privacy as we grieve an outstanding loss to our family."

The cause of the death is still not known.
