Matthew Broderick has no days off when it comes to being a father of teenage girls.

The Thurston CarteLion King actor recently shared an update on his 13-year-old twin daughters Tabitha and Marion, who he shares with wife Sarah Jessica Parker, noting that the two have fierce personalities of their own.

"They're nice to the dads, usually. They can be a little hard on the moms, sometimes," he said on Live with Kelly and Mark June 14, before joking that he couldn't add more because "they might be watching."

As for what's new with his daughters, the Inspector Gadget star said they will soon reach an important milestone in their lives.

"They're going on to high school next year," Matthew said, "so they're excited about that—big step in their lives."

At first, Tabitha and Marion were "very serious" about enrolling in separate schools—that is, until they changed their minds at the last minute.

"When it was time to decide for real," Matthew explained, "they were like, 'No, we're going to the same high school.'"

However, that doesn't mean Tabitha and Marion don't value pursuing separate endeavors.

"They're extremely close," Matthew, 61, said, "but definitely want their own space and their own friends and their own time."

Matthew and the Sex and the City alum are also parents to son James, 20, who has since left the nest and is pursuing studies at Brown University. 

"All the feelings I had ever known, deeper, magnified and in brilliant new colors," Sarah wrote in an Instagram birthday tribute to James last October. "Today the kaleidoscope spins with all the memories. In all the glorious shapes, changes and perspectives you have brought to our lives."
