Michael Strahan is beaming with pride after watching his daughter Isabella Strahan finish treatment for her brain tumor.
On June 16, the Good Morning America co-host, 52, posted a video on Instagram of his 19-year-old daughter ringing the hospital bell and celebrating the end of her chemotherapy treatment. The model was diagnosed with a large medulloblastoma — a type of malignant tumor — in her cerebellum in October 2023.
In the clip, Isabella is surrounded by family and friends at the Duke Children’s Hospital & Health Center in Durham, North Carolina. They cheer her on with balloons, bubbles, and homemade posters.
“Ring the bell three times well. It’s a toll to clearly say my treatment is done, this course is run and I’m on my way!” she said as she rang the bell with a big smile on her face.
“@isabellastrahan you are a SUPERWOMAN! Ringing that bell, finishing chemo and on your way! ??????,” Strahan wrote. “You continue to fight with a smile on your face, strength, and determination. I am one proud Dad! Love you, Bella ????”
In the comments section, tons of fans and celebrities left congratulatory messages for Isabella, including well wishes from Mark Wahlberg, Flavor Flav, Derek Jeter, Boris Kodjoe, Olivia Munn, Terry Crews, Alex Rodriguez, Yara Shahidi, Michael Phelps, Maria Menounos and more.

On June 14, Isabella released the latest installment of her YouTube series, documenting her final round of chemotherapy. Since her diagnosis, she’s gone through six weeks of radiation, four rounds of chemotherapy and three brain surgeries.
“I officially finished my chemo! Yay! This was a long journey, but I made it,” Isabella said with a smile and thumbs up. “Now I have to recover and get back to my usual state, which is gonna take a long time but done with treatments.”
