He's One Direction's go-to guy!
Zayn Malik even said "He's our love guru," according to The Mirror.
James is happily engaged and father to a wee baby, so clearly knows a thing or two about keeping the ladies interested.
"James gives great advice," said Harry.
“James knows everything about every situation,” agreed Louis. “He’s such a lovely fella, too.”
While Niall admitted that Mr Corden “looks after” them all.
Maybe that's what he was doing at One Direction's New Year's Eve party; sorting out their love dilemmas and giving them all a shoulder to cry on, while they were surrounded by girls who were all having a great time and there specifically to see them...
Yeah, we don't imagine they keep James too busy with their girl problems.
