It's so random they're friends!

Harry Styles invited Cindy Crawford's children Presley and Kaia to the One Direction concert on Saturday in Canada, and during his downtime, the boybander went cliff diving with the supermodel's 15-year-old son.

The singer began hanging out with the Crawford clan earlier this year, and although we would think the 20-year-old would want to be friends with people his own age, apparently he has a lot of shared interests with the teenagers. The other month, Presley and Harry got together for a surfing session, and another time they made pizzas together. Bromance!
