Paris Jackson couldn't be prouder of her mother—and with good reason! The 18-year-old daughter of Michael Jackson took to Instagram on Tuesday to celebrate Debbie Rowe's completion of chemotherapy treatment for the breast cancer she was diagnosed with in July.

The photo shows Rowe smiling while holding a handwritten sign announcing the end of her chemo treatment. "Chemo. Done!" the paper reads.

"My badass mom, kickin butt n takin names," Jackson captioned the 'gram. "Ain't she f—in' fabulous????"

Although they were at one time estranged, mother and daughter are now closer than ever. In fact, in an October interview with ET Rowe admitted Jackson's the "reason she gets up in the morning."

"She's my rock, she's amazing," she said. "She's been with me the whole time."

Rowe, a dermatology nurse, and the late King of Pop were married from 1996 to 1999 and had two children together, Paris and Prince Michael, 19.

Congratulations and best wishes, Debbie!
