Paris Jackson Debbie Rowe

Michael Jackson‘s daughter Paris Michael Katherine Jackson, 18, published an Instagram.com photo, revealing her biological mother is battling breast cancer.

Paris posted the photo of herself and Debbie Rowe, 57, on Instagram.com on Friday. Rowe is currently undergoing chemotherapy, which robbed her of her long blonde hair.

“I’m a fighter because she’s a fighter. Love you mom,” Paris captioned the image.

Contrary to published reports that mother and daughter were “estranged” and recently reunited, Paris reconnected with Rowe within 2 years after Jackson died of an accidental drug overdose at age 50 in 2009. The 2 have remained close ever since.

Rowe, a former registered nurse, married Jackson in 1996. They divorced 3 years later.

Rowe is the biological surrogate mother to Michael Jackson’s 2 oldest children, Paris and Michael Joseph Jackson Jr., aka Prince, 19.

The children’s biological father is rumored to be Jackson’s longtime friend Dr. Arnie Klein, who passed away in 2015 at age 70.

Jackson’s 3rd child, 14-year-old Prince Michael Jackson II, aka “Biji”, was born to an unidentified surrogate mother. Biji’s biological father is also unknown.
