The famous country music couple won the King and Queen titles for hilarious Halloween costumes this year - hands down.
Once again, they've given fans a good laugh with their matching Halloween attire. This year was no different.
But before they got to the main event, Caroline posted some throwback pics to Instagram that went down Halloween memory lane.

She captioned the post:
"5 more days until Halloween! 5 more days until I get to torture Luke with another ridiculous costume... he secretly loves it."
The ten pictures mostly featured the year they went with senior citizens costumes.
They had switched roles so Caroline was the old man while Luke looked hilarious wearing pink shades, a blue dress, and curlers in his head.
There were also flashbacks to the couple in an inflatable T-Rex costume, and a turkey and deer duo.
Before giving fans the full picture for this year, Caroline posted a video of just her face in costume.
Her location for the photo confirmed the obvious. She was a squirrel. As to what Luke would be, fans would have to wait since they saw him in the background not yet dressed.
Then another post showed Luke in a bright yellow and brown acorn outfit. The two looked extremely comical.
Luke didn't only share his inflatable costume love with his family, he also appeared on "Live with Kelly and Ryan" as an eagle. He was joined by "American Idol" co-judges Lionel Richie and Katy Perry.
Despite the saying looks can be deceiving, the pair certainly appears to have a happy relationship.
Back in 2016, they held nothing back as they gave cameras full PDA on the red carpet. Luke was co-hosting the ACM Awards in April.
He walked with his wife and the two snuggled close, basked in several photos together, and even lip-smooched in for the cameras.
When Luke did an interview in April 2018, he spoke about how the two were seemingly destined to be together. They broke up in college before a chance encounter almost six years later.
They had two sons, Bo and Tate. Then they later adopted two of Luke's nieces and one nephew following the death of his sister and his brother-in-law.
Luke opened up about his marriage in another interview. He said: "We get into it, we fight, we figure it out." He later added, "we just try to be normal and enjoy the ride of this."
With their Halloween costumes, they certainly seem to be having fun together.
Other celebrities joined in on the fun and many also shared adorable photos of their kids enjoying Halloween.
See what Harry Styles pulled off when he put on a Sir Elton John look.
And Heidi Klum spent ten hours going all out as a very old woman for Halloween.
Neil Patrick Harris and his family stole the show with a full family decor as they pretended to be the Hitchhiking Ghosts.
Meanwhile, Dwayne Johnson also showed of his cute little girls. They were all dressed as skeletons.
The Queen herself, Beyonce Knowles took their royalty to the Halloween stage. They included little Blue Ivy in the setup as Imani Izzi. Beyonce was Queen Aoleon, and Jay Z was Prince Akeem from the film "Coming to America."
