Michael Strahan's 19-year-old daughter had an epic fangirl moment.

Isabella Strahan, the daughter of the "Good Morning America" host, recently took to her eponymous YouTube Channel to share a vlog about the day she "went total fan girl with Bryson Tiller," whose songs she listened to during her radiation sessions.

In her vlog, she described the incident as the "best surprise ever." As seen in the intro of her 13th YouTube upload, she got the surprise of her life when the R&B/Soul singer appeared in front of her in their home.

Isabella, giggly and all smiles, welcomed Tiller with a big hug and said, "It's Bryson Tiller!"

 

Isabella's fangirl moment was made possible by her supportive dad. Before the "Don't" singer came to surprise her, he had a "top secret meeting" with her father.

"If she'd have been in her pajamas when you walked in here... we would have a problem. She wouldn't forgive us," Michael told the singer.

After the talk, Tiller walked into the Strahans' kitchen to meet his dear fan whose jaw dropped upon him.

While hugging each other, she said, "It's Bryson Tiller! You're my favorite person ever... Thank you... I'm sorry, I usually don't cry like this. It's so nice to meet you."

Meanwhile, seeing how happy his daughter was jumping up and down in excitement, Michael joked, "You haven't moved this much in months!"

He then revealed that Tiller flew in to visit his daughter after he learned about Isabella's health battle from one of her vlogs.

Michael also teased Isabella, saying, "You are fangirling right now. All your coolness is out the window!"

During Isabella and Bryson's time together, they built a flowerpot Lego set, which the former later posted on her now-expired Instagram Story.

 

The young YouTuber started her channel in January. In her first vlog, she shared a story on how she learned about her Medulloblastoma diagnosis in the fall of 2023. She was just starting her freshman year of college at the time.

Isabella revealed in her vlog that she celebrated her 19th birthday in October by having a tumor removed from her brain.

"I hope to inspire many by sharing my story, this is just the beginning," she wrote in her vlog's description.

She added, "All proceeds will go towards The Preston Robert Tisch Brain Tumor Center at Duke."
