The couple and their 18-month-old son Silas dressed up as characters from Timberlake’s new movie Trolls, E! News reports.
Biel posted a photo of the adorable family posing for the camera (except a shy Silas) and wrote, "Happy Halloween from Poppy, Branch and lil Branch. We be Trollin'..."
Timberlake shared the same photo and poked fun at himself for his self-promotion saying, "Shoutout to @jessicabiel #2BranchsandaPoppy #Trolls #didIuseaholidayforselfpromo Happy Halloween, everybody!!!!"
The singer shared another photo of the family starting their trick-or-treating. "When you make your whole family dress up as the characters from the movie you're in but your wife secretly loves it and your son won't keep his troll wig on...," JT captioned the picture.
According to Timberlake, his son is a huge fan of the Trolls movie.
"He knows all the characters," Timberlake gushed during an interview. "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!'"
