It wouldn't be Halloween without an epic costume from Justin Timberlake's family, and they totally came through this year. This season, Justin, Jessica Biel, and their 3-year-old son Silas channeled Robin, Harley Quinn, and Batman, respectively — but with a twist! Instead of the usual getups we're used to seeing everywhere, the trio opted for the Lego version, and they totally crushed it! "Out here fighting crime in these streets," Justin wrote on Instagram. However, if we had to choose, we'd say Silas's costume is our favorite!
