"We be Trollin'."

Justin Timberlake takes movie promo super seriously.

The pop star/actor went trick-or-treating with wife Jessica Biel and son Silas on Monday night dressed as Branch, the character he voices in the movie Trolls. Silas is a mini-Branch while Biel took on Anna Kendrick's role of Poppy.

"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," Timberlake captioned a photo of his adorable family on Instagram, poking fun at his self-promotion with the hashtag #didIuseaholidayforselfpromo.

 

Biel, meanwhile, posted a posed picture of the family (though the private parents both kept their son's face off the photo-sharing site) with the caption "We be Trollin'."

 

Happy Halloween from Poppy, Branch and lil Branch. We be Trollin'...
