'At least twice a week on tour, we shut the door to the outside world and have family dinner,' the 39-year-old captioned the snap.
A fan was quick to reply and question why she would post a private moment on Instagram.
The Funhouse singer was clearly not impressed and fired back: 'Yes, I like to promote healthy stuff.
'I also like to remind people to stop being TOTAL DOUCHE BAGS TOO. Consider this your reminder,' she concluded.
The reply caught the fan off guard, who responded: 'and well damn, I was coming to see ya Sunday night in Nashville.. still love the music.'
Pink quipped back: 'That doesn't change my answer. That just makes you confused.'
