What kind of advice can Clint share with the young heartthrob? Of all things, Harry is reportedly getting fitness advice from the older star, taking up Krav Maga (a combo of boxing, martial arts and wrestling) on the advice of the 84-year-old actor.
A source tells the Daily Star: "Clint spoke to Harry about his future in Tinseltown. They discussed movie projects and then got on to the subject of achieving an action hero's physique. Clint had plenty to say on what Harry should do if he ever wanted to be considered leading man material."
Seems a couple of Harry's bandmates are hooked on the workout plan too, as the source noted: "Louis and Liam are also raving about KM now. They've even been having a body competition – comparing their biceps over Instagram!"
