The 'Nashville' star was travelling with her two-year-old daughter Kaya - her child with her with fiancé, former world heavyweight champion Wladimir Klitschko - when the toddler had to use the rest room.

However, the toilet trip turned turbulent when little Kaya had an accident before reaching the seat.

But Hayden didn't stress and she and her daughter grabbed some tissues and set about cleaning up so the rest room was ready for the next user.

Tweeting about the mishap, Hayden posted a photo of her and Kaya on clean up duties.

The accompanying tweet read: "Aaaand then ur daughter pees on the floor of the airplane bathroom But look at that baby girl helping momma clean (sic)"

Previously, Hayden bravely opened up about having postpartum depression when Kaya was a baby but she thinks the experience has made her a "better mom".

The 27-year-old actress said: "It takes you a while and you feel off. You don't feel like yourself. Women are so resilient, and that's the incredible thing about them. I think I'm all the stronger for it. I think I'm a better mom because of it because you never take that connection for granted."
