The former dermatology nurse was diagnosed with breast cancer in July.
Jackson has been by Rowe’s side during her cancer battle, following the mother-daughter pair’s reconciliation in April 2013. Jackson previously shared a photo of her kissing her mum’s head along with the caption, “I’m a fighter because she’s a fighter. love you mom.”
“[Paris] is my rock, she’s amazing,” Rowe told Entertainment Tonight in an October interview. “She’s been with me the whole time. She was there. First phone call, [it] took her 30 seconds [to reach out] when she found out.”
Rowe was married to the late King of Pop from 1996 – 1999, and had two children together: Paris and Prince Michael, 19. She is not the mother of Jackson’s third child, Prince Michael II, 14, who was born to a still-unidentified surrogate mother.
