Ethan Hawke didn’t tell his daughters he was going to be in Taylor Swift’s “Fortnight” music video.

Ethan Hawke says he didn’t tell his daughters he was appearing in Taylor Swift’s “Fortnight” music video.

“You tell my teenage daughters that I’m going to meet Taylor, and everybody at school is going to know,” Hawke said during an appearance on “The Late Show with Stephen Colbert” on Monday. “No, I signed an NDA.”

The actor also joked that “the look on their faces was one of profound disappointment” once they learned about his cameo.

“‘Don’t pay attention to my dad. My dad is an idiot. You should be calling me,'” Hawke said, mimicking his daughters’ reactions. “Taylor belongs to them. I can’t have that on them, so I had to low-key it.”
