Pink's husband Carey Hart has taken to Twitter to unleash in a rant against American airline company, United Airlines.
The former motocross racer wrote, 'This it, I will never spend money on @united ever again. You are so unprofessional it’s out of control.
'To N. Ayala in San Francisco, your patronising of a customer is repulsive. Save your money people, this airline isn’t worth the headaches.'
It's unclear exactly what went down on the flight.
United Airlines quickly replied to the Tweet, writing: 'This is extremely concerning to hear, Carey. Can you please DM your confirmation number and further information on your experience? We would like to assist right away. ^BK'
Carey's Tweet has been retweeted several times, and liked by over 300 people.
The 37-year-old's rant comes just weeks after he got into a heated argument with Australian fans after exposing his son Jameson with hand, foot and mouth disease to others.
Taking to Instagram last week, the former motocross racer joked it was a 'miracle' that Pink's band and crew did not catch the disease during her recent tour Down Under.
'Glad to be back with the family after a couple days away racing. Jameson is back to normal and Willow is healthy as well,' he began.
'Can you believe that of the 80+ crew and band on tour, wife, daughter, nannies, myself, and restaurant patrons; no one go HF&M???? It must be a miracle!!!!!!!!'
Hart added the hashtags: 'GuessThePediatricianKnowsHisSh*t,' 'LittleFuelForTheFire,' and 'HappyMonday.'
