Taking to Instagram, Mel B confirmed her father, Martin Brown, had passed away after a five-year battle with cancer.
He was 63.
Alongside a touching black and white photo of Mel and her sister holding their fatherโs hands, the former Spice Girl penned: โIt is with great sadness after a 5yr battle to multiple myeloma cancer our loving father Martin Brown passed away age 63 peacefully yesterday.โ
โBoth of us his children were by his side and would like to say thank you to St Gemmaโs and all the doctors and nurses for there amazing care and support over the years.
Please respect our privacy and let us as a united family grieve.โ
โWith love and respect. Melanie and Danielle Brown x Be Free Dad,โ the poignant post concluded.
Myeloma is a form of cancer that forms from plasma cells in the bone marrow.
It also appears the 41-year-old has made amends with her younger sister, with the pair having a complex relationship and a long-standing feud.
Earlier in the year, Danielle shut down rumours that she and Mel had buried the hatchet.
โJust 2 put the record strait! Ive Not seen my sister for 8 years,there is no family reunion planned,it is what it is #dontbelivewhatyouread,โ she explained on Twitter.
Melโs family rift first arose in 2007 after her mum, Andrea Brown, and sister reportedly disapproved of her marrying her now husband, producer Stephen Belafonte.
Last year, the mother-of-three told new! magazine that she had been spending time with her estranged family members.
โShe came down yesterday, saw the kids and watched the show [Lip Sync Battle UK, which Mel starred on]. Then we hung out and went for dinner with the kids. Family is family. Thereโs no point talking about that,โ she told the publication of her mum.
