Ariel and Levi attempted to recreate the looks that Kid & Pamela wore to the 29th Annual American Music Awards.
"Don’t worry, we’re also concerned by the accuracy," she wrote on the pic (seen here). Many of her followers complimented the Modern Family star on the costume, with one saying "Bwuhahaha! Spot on."
Nicky Hilton Rothschild did something similar when she dressed up as her sister Paris from when she turned 21 in 2002 on Friday night.
This isn't the only costume that Ariel and Levi wore this year, as they were spotted dressed as two characters from The Incredibles while leaving a party on Friday.
The 21-year-old's look was fairly spot on compared to the character of Helen Parr, originally voiced by Oscar winner Holly Hunter when it was released in 2004.
