Michael Jackson's daughter, Paris-Michael Jackson, recently posted an image of her and her mother after the two had been estranged for years.
Jackson, 18, posted a photo with her mother, Debbie Rowe, on Instagram on Friday.
In the photo, Jackson kisses Rowe, who is bald, as she's undergoing chemotherapy.
Rowe, 57, revealed that she was diagnosed with breast cancer in July.
"I'm a fighter because she’s a fighter," Jackson captioned the picture, adding, "Love you mom."
Jackson is the younger of two children from Rowe and Michael Jackson's relationship. The two, who were married from 1996-1999, also parented Michael Joseph "Prince" Jackson Jr., 19.
Michael Jackson's third and youngest child, Prince Michael "Blanket" Jackson, was born to a still-unidentified surrogate mother, People reported.
After Michael Jackson's death in 2009, the King of Pop's mother, Katherine Jackson, was granted guardianship of his children.
Rowe, who was granted supervised visitation rights with her children, "steered clear of the family, except for occasional visits with her kids," according to People.
The mother and daughter went years without communicating.
Rowe and Paris Jackson publicly reconciled in 2013 and reportedly increased communication earlier this year after Rowe's cancer diagnosis.
