Finding the perfect couple's costume is no easy task. Sure you could go as peanut butter and jam or Fred and Wilma Flintstone, but to really win Halloween, you need to be creative!

Jessica Simpson and husband Eric Johnson came up with an adorable costume and it's a throwback that we can all appreciate.

It's clear Halloween is a big deal for the family. Earlier last month, Jessica shared a picture of her kids with their jack-o-lanterns on Instagram, with the caption "I ain't afraid of no ghost!!"

Last year, Jessica and her husband went as Danny Zuko and Sandra Dee from Grease and we didn't think anything could top that adorable couple's costume.

"Danny Zuko and "Sandra Double Dee" 👻 #AboutLastNight," she wrote on Instagram.

She also shared her kids costumes from 2016 in an adorable family photo.

"When your kids are old enough to choose their own costumes ... #HappyHalloween from my parrot & octopus! 🎃" she wrote.

This year the 37-year-old singer, turned entrepreneur posted on Instagram her and her husband sitting in costume on their porch decorated with pumpkins and haystacks.

Gone was her long blonde hair and her signature look was replaced with a white beard.

This year the couple dressed as Willie Nelson and Willie's old collaborator Waylon Jennings.

Jessica completed the look with an American flag bandanna and a pair of patriotic leather boots.

Much like their outlaw country singer muses, who released a duets album called Waylon & Willie in 1978, Jessica and Eric carried guitars in their lap.

It's clear that Jessica is a fan of the 84-year-old singer.

"You've got a couple more years on me baby, that's all...." @willienelsonofficial" she posted on her Instagram with a photo of her and the music legend.

The family also shared a photo that included their five-year-old daughter Mawell and four-year-old son Ace.

Maxwell was Belle from the 1991 version of Disney's The Beauty And The Beast, while her younger brother was a cowboy.
