Singer Niall Horan snapped a photo of an apology note from two gay dads taking their 18-days-old baby on its first flight.

The note, which included a photo of the baby, read: “Hi Stranger. My name is Marit. Today, I’m 18 days old. I’m flying home to Europe with my dads. This is my first flight ever. I will do my utmost to be on my best behaviour to ensure that you have a peaceful flight. I would like to apologize in advance if – I for any reason loose [sic] my cool, my temper, my ears hurt or my tummy gets fussy. I think my dads are more nervous than I am, so they made you this goodiebag.”

“Had the coolest little goodie bag on the plane with this letter enclosed. Marit was quiet as a mouse for 10 hours. Goodluck to both dads,” Horan tweeted.
