The Sister Sledge star - who passed away at her home on Friday (10.03.17) - will have her cause of death listed as "natural causes" after her doctor signed off on the cause of death.

Whilst it has not been made public what caused her tragic death, it is thought an autopsy won't have to take place but it is thought it could be related to a pre-existing medical condition, TMZ reports.

It comes after the remaining members of Sister Sledge - Debbie and Kim - vowed to carry on performing without their late sister.

They said in a statement: "Sister Sledge will continue with their 2017 concert schedule. Sister Sledge - Debbie, Kim and the Sledge family would like to express our deepest gratitude to all who have extended their love and support during this difficult and challenging time of mourning, in the wake of the passing of our beloved sister Joni Sledge.

"Joni was a beautiful person, phenomenal artist and producer, a brilliant business woman and a powerhouse! One of her greatest loves and joys was performing live with her family. In the spirit of Joni's powerful strength of character, zest for life and spreading joy through music, we are committed to continuing her legacy.

"Therefore, in this new 2017 concert season, and in the true Sister Sledge family tradition, we will embrace and celebrate Joni, dedicating every concert in honor of her remarkable and beautiful life. WE ARE SISTERS. We are one... We are Flo's daughters. We are Family! WE ARE WAMOWS! (sic)"

Joni was found dead at her home in Phoenix, Arizona last week and the sad news was announced in a family statement released through the band's publicist Biff Warren.

It read: "Yesterday, numbness fell upon our family. Pray for us as we weep for the loss of our sister, mother, aunt, niece and cousin Joni Sledge. We thank you for privacy as we hurt for her presence, but also for embracing her radiance and the sincerity with which she loved life."
