They really went all out!

Everywhere we turned celebs were dressing up in costumes to take their kids trick-or-treating, and it's hard to pick whose outfit was our favorite! We love Gisele dressed up as Luigi to her son Benjamin's Mario, but we love Justin Timberlake and Jessica Biel as characters from the movie Trolls with son Silas the most!

We couldn't help but notice that recently separated couple Jennifer Meyer and Tobey Maguire put their differences aside for the sake of their kids Ruby and Otis, and we bet pal Gwyneth Paltrow gave them some tips on conscious uncoupling.

Our trained eye also spotted the fact that Orlando Bloom and his son Flynn were out on the candy hunt with Katy Perry's dog Butters! We wonder where KP was for the occasion? We love she loves the holiday!
