“Our oldest daughter’s in college. Obviously, that’s been shut down, but she’s in New York City. She had COVID really early on along with her roommates and got through it fine,” Damon, 49, said on SPIN 1038’s “Fully Charged.”

Damon still considers 21-year-old Alexia, who is the daughter of wife Luciana Barroso and her first husband, to be one of his own kids.

“So I shouldn’t say our whole family’s together,” Damon continued. “Of our four kids we’ve got the three younger ones and our oldest one [Alexia], we’ll reunite with her at the end of the month. But everybody’s OK.”

The “Contagion” star shares daughters Isabella, 13, Gia, 11, and Stella, 9, with Barroso. They’ve all been quarantined together in the small town of Dalkey after Damon’s movie was delayed.

Detailing how he and his family ended up in Ireland, Damon noted, “I’m in the middle of a movie that I shot the first half in France and we were moving to Ireland and kind of right when we arrived in Ireland, the movie was shut down.”

“The Martian” star also admitted that his family has been incredibly lucky with their Irish setup because they brought teachers along with them.

“Obviously what’s going on in the world is horrible, but for my family, it timed out,” Damon shared. “I’m with my whole family, I’ve got my kids, and we had teachers with us because we were planning on missing school for about eight weeks, so we’ve got what nobody else has, which is actual live human beings teaching our kids.”

“All their friends, the schools are all shut down back home and the kids are doing remote learning, so we feel guilty,” he confessed. “We’ve got this incredible set up in this place, which is gorgeous.”
