Former Arrow star Colton Haynes and his beautiful famous friends go hard for Halloween. Haynes is unrecognizable in his Little Mermaid Ursula costume. You may have partied next to him last night and not even known. He hit the town with Ally Maki (as “Chandelier” Sia), Fanta Sesay (as Chun-Li from Street Fighter), Chloe Bennet (as a grocery bag), and Emily Bett Rickards (as Sailor Moon). #SquadGoals. Last year Haynes went as Fiona from Shrek. He was concerned that he couldn't top that awesome costume, but we think he succeeded.
