âHooray for Halloween!â he captioned a family photo on Instagram.
In the adorable snap, Harris is dressed as actor and comedian Groucho Marx, complete with a grey wig, cigar and a thick, burly moustache. His husband, David Burtka, is decked out in a full suit, posing as Charlie Chaplin, while their six-year-old twins, Harper and Gideon, are dressed as the iconic stars Marilyn Monroe and James Dean.
Just last month, Harris appeared on âLate Night with Seth Meyersâ and revealed that he takes dressing up for Halloween âvery seriously.â But now that the twins are getting older, Harris joked, âTheyâre starting to have more of an opinion, which is a little bit annoying.â
However, last yearâs âStar Warsâ costume was an easy one to pull off since both twins are big fans of the film franchise and needed no persuading.
In the past, the family has also gone as Gotham City characters.

And as the cast of âAlice in Wonderland.â
But our favourite, by far, has to be from 2011 when Harper and Gideon were just one year old and took on a Neverland theme with their parents.
We canât wait to see what group costume they come up with next!
