Jessie James Decker had a bone to pick with a fellow airline passenger — and she wasn’t keeping her nose out of it.

The country singer sparked a social media debate after sharing a video of herself covering her nose as a bare foot appeared beside her airplane seat, then dousing the foot with some sort of spray.

“Someone’s foot smells so bad on the plane,” the text over the video read.

Decker had one question for her 4.4 million followers on Instagram.

“Before you come at me…What would you have done?” she captioned the post.

Social media users wasted little time weighing in, and plenty of commenters had no sympathy for whoever was responsible for the alleged odor.

“The nerve of some people!” one user fumed.

“I’d do just what you did!!! Spray the stinky foot!!!” another cheered.

One commenter called for a much harsher penalty, writing, “They should’ve been escorted off the plane.”

A self-described former flight attendant also criticized passengers who treat airplane armrests like personal footrests.

“As a past flight attendant, when I saw people put their feet on the arm rest. I immediately told them no, this isn’t their home. Respect the plane & people around you. That is so F in nasty. I would have smacked his foot with my elbow.”

But amid the outrage, others questioned whether Decker really sprayed a stranger — or whether the mystery foot belonged to her husband, Eric Decker, a former NFL wide receiver. The couple married in 2013.

“Please tell me that’s Eric’s foot and not some random person’s foot!” one commenter wrote.

“I’m guessing that’s Eric’s foot? You are far too sweet to do that to a stranger…” another speculated.

“That better be your husband. I would’ve moved!” a third user added.

One follower was convinced the clip might have been a joke between the couple and wrote, “You’re being silly, right? It’s your husband behind you.”

Others had their own ideas for dealing with a rogue foot in the cabin.

“Tickle tickle!” one user suggested.

“I would’ve pulled out … [a] sharpie and started drawing,” another joked.

“You should have pretended to sneeze then sprayed his foot,” a third commenter proposed.

Decker did not identify whose foot appeared in the video.
