See More Celebrity Kids on Halloween

NPH's family just came through again for Halloween!

Neil Patrick Harris, hubby David Burtka and the couple's adorable twins, Harper and Gideon, always crush it with their annual costumes -- and this year, they definitely didn't disappoint.

The former "How I Met Your Mother" star just unveiled their 2016 looks on Instagram, showing the foursome dressed as Hollywood icons inside an empty movie theater.

The looks: Neil as Groucho Marx, David as Charlie Chaplin, Harper as Marilyn Monroe and adorable Gideon as the original "Rebel without a Cause," James Dean.

We can't get over their 6-year-old daughter's sassy pose, as she rocks the legend's famous "Diamonds Are a Girl's Best Friend" dress from "Gentlemen Prefer Blondes."

Harris opened up about taking the holiday "very seriously" in an interview with Seth Meyers last month.

"They're starting to have more of an opinion. It's a little bit annoying," he told the late night host. "I'm trying to do Jedi mind tricks on them, like, 'Hey, look at that, that's a cool idea.'"

He added that he was slightly concerned about what they wanted to wear to school as well, as Harper wanted to dress as a "goth whore" from "Monster High," while his son was set on an impractical R2-D2 costume.

In years past, the Harris clan has dressed as characters from "Star Wars," "Peter Pan," the Universal Monsters universe, "Alice In Wonderland" and Batman. See those in the gallery below!
