NPH's family went uber artsy for this year's celebrations, dressing up as four famous artists in history. Set in a decadent frame, the creative photo the actor posted to Instagram featured Harper as Frida Kahlo, Gideon as Andy Warhol, David as Salvador Dali and Neil as Pablo Picasso.
"Welcome to the 2019 Burtka-Harris Boo-seum of Art. Audio guides are available in the gift shop. #happyhalloween @dbelicious," Harris wrote.
When the two were just wee little ghouls, they got to portray Alice in Wonderland and Wizard of Oz characters among other fantastical looks, but as they’ve gotten older, Gideon and Harper have become as enthralled with the holiday as their dads. Last year, they dressed up as characters from Disney's Haunted Mansion, and their epic freak show spectacular in 2017 gave us the creeps in the best way possible.
Let's be honest -- these four always slay Oct. 31. Click through the gallery below for the family's fangtastic Halloween photos through the years.
