“It feels appropriate, although slightly narcissistic to make my son dress up as a character that I play,” Timberlake said on the rainbow carpet premiere of Trolls.

He added, “But I don’t care what you think, we’re doing it.”

Silas has seen the movie. “He knows all the characters,” Timberlake revealed. “When I first showed him the movie—I was able to show him at home, that’s one of the perks—as soon as it was over, he said, ‘Trolls again!'”

The cast of the animated film also stars Zooey Deschanel, Russell Brand, Gwen Stefani, Christine Baranski and more.

Trolls opens in theaters on Nov. 4.
