The ladies told Sunday World recently, "We've met the boys and seen how humble and down-to-earth they are, it's clear they are still so real."
No surprises there. And that realness is something 5H wants to keep in mind too, with Dinah explaining, "It makes us want to make sure we don't lose ourselves in this business, that's what we learned from them."
1D's biggest piece of advice? "Stick together," which is exactly what they've done over the years (breakup rumors, be damned!). The ladies explained, "Harry told us, 'Through everything you should stick together. Make sure you never break your bond.' I think that was good advice."
Well, it's definitely worked for One Direction!
