Entertainment Music Justin Timberlake and Son Silas Dress as 'Branch and lil Branch' from 'Trolls' — and Jessica Biel Is Poppy! "When you make your whole family dress up as the characters from the movie you're in," Timberlake wrote By Karen Mizoguchi Updated on December 2, 2020 02:47 AM Share Tweet Pin Email Photo: Instagram The family that Trolls together, stays together. It appears Justin Timberlake chose this year’s Halloween costumes for wife Jessica Biel and 18-month-old son Silas Randall. “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,” he captioned his Instagram photo on Monday. The Timberlakes dressed up as animated characters from the singer’s DreamWorks film Trolls with the father-son pair going as “Branch and lil Branch,” Biel, 34, described for her own Instagram caption. The actress rounded out the perfectly adorable bunch by opting for the role of Princess Poppy. “We be Trollin’,” the mother of one also wrote. In Trolls, curmudgeonly Branch (voiced by Timberlake) and Poppy (voiced by Anna Kendrick) set off on a journey to rescue her friends after Troll Village gets invaded by Bergens, large creatures who never feel happy but discover that they can feel happy for a moment if they eat a Troll. Timberlake, 35, previously revealed his idea for the family’s Halloween costume during the film’s press tour. “I’m trying to put together a family theme, I may pull some rank and see if we can, maybe we’ll be Trolls. Maybe we’ll be some characters from the movie,” he told Extra‘s Mario Lopez at the Los Angeles premiere last week. Trolls opens in theaters Nov. 4.
