Jessie James Decker takes issue with intruding bare foot on flight

Jessie James Decker has sparked a social media debate after sharing a video of herself covering her nose as a bare foot appeared beside her aeroplane seat.

The country singer then doused 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 barefoot intrusion.

Decker did not identify whose foot appeared in the video, but there was plenty of speculation that it might have belonged to her husband.

The Secret Sauce author and American footballer Eric Decker have been married since 2013. They share four children: Vivianne, 12, Eric Jr., 11, Forrest, eight, and Denver, two.

The incident comes amid rumours that the country singer is set to join the cast of The Real Housewives of Nashville.

"I have friends coming up being like, 'Are you doing Real Housewives of Nashville?'" she told Us magazine.

"I think it's because I did Watch What Happens Live, and Andy was being funny and teasing, and I think people got excited."

Andy Cohen, host of late-night talk show Watch What Happens Live with Andy Cohen, is the creator, executive producer, and reunion host of The Real Housewives franchise.
