Strahan made the announcement alongside a picture of the 18-year-old posing with a cake that featured the school's colors and logo. He added in the caption of the post: "FIGHT ON, @isabellastrahan! #ProudDad #USC."

The former NFL star previously teased the announcement alongside photos of Isabella's graduation day where he recognized her as someone who is  "intelligent, beautiful, and hard-working." The announcement comes shortly after Straham shared that Sophia would attend Duke University in a previous post.

"You are intelligent, beautiful, and I can’t wait to see all of the amazing things you are going to accomplish at Duke," Strahan wrote of Sophia on May 27.

Strahan shares Isabella and Sophia with his ex-wife Jean Muggli. He is also a parent to Tanita and Michael Jr., whom he shares with his first wife Wanda Hutchins.

The TV personality previously shared with PEOPLE that being a father of four teaches him something new every day.

"Sometimes life gets serious for us as adults, but looking at my kids, it lets me know that you're allowed to have fun — you're allowed to have mindless fun," he told PEOPLE in 2016. "And you're allowed to be yourself and act like no one is watching. I think that is the most valuable lesson that I've learned from them. They keep on teaching me every day, so I'm always willing to learn."

Apart from Isabella and Sophia's graduation day, he also celebrated Isabella's runway modeling debut at the Sherri Hill fashion show in April 2022.
