Justin Timberlake is so excited about his upcoming movie Trolls that he made his entire family dress up like the characters for Halloween. While the singer looked barely recognisable alongside his wife, Jessica Biel, it was their son, Silas, that stole the spotlight with his little ensemble and sweet curls. "Happy Halloween from Poppy, Branch and lil Branch. We be Trollin'..." the actress captioned the snap of the trio. Talk about cuteness overload!
