I think it was in Private Eye when there was a story about someone flying first class NY - London, with James Corden sat in the next seat over. In the seat behind was a woman with a baby. The narrator expected Corden to have a diva tantrum about having a baby spoiling his time in first class, but apparently he kept silent, just put some headphones and an eyemask on and went to sleep while the woman spent the whole flight dealing with the kid.
The twist was revealed at the end, when they all got up to leave and the narrator realised it was Corden’s own wife and kid he had been ignoring.
