Michael Strahan is embracing happy moments between his lovely daughters.

On Tuesday (May 21), the GMA co-host shared a cheerful video of his twin daughters Sophia and Isabella and their cute dog doing a challenge that's gone viral on TikTok. This moment was also captured as Isabella is currently battling medulloblastoma.

"These three are amazing but who is my favorite🤔? LOL❤️❤️," Michael wrote in the caption of the post.

In the video, the sisters are seen sitting in front of each other with their dog nearby. As they each place one of their hands on the other's, they anxiously await to see if their dog will follow suit and place a paw on top of theirs.

Seconds later, the brown dog raised one paw and put it on their stacked hands.

Ecstatic by their dog's participation, the twins immediately turned to the camera with huge smiles while giving their pooch well-deserved hugs and rubs.

In January, Michael sat alongside Isabella as she opened up on "GMA" on how her life had changed since being diagnosed with medulloblastoma.

A month later, he shared an update on her condition while undergoing chemotherapy.

While Michael said the 19-year-old has been "fighting through," the process continues to be challenging.

"The last three days have been a little rough because she had a fever that kind of comes and goes," he explained. "I had to take her to the hospital and thought she'd come home a few hours later. ... It's been three days, but hopefully she'll be home today."

Isabella is a twin with her sister Sophia, 19, whom Michael shares with wife Jean Mugglie. He is also dad of  Michael Jr., 29, and Tanita, 32, from his first wife, Wanda Hutchins.
