Prince William is said to have offered his brother an incredible piece of advice after his mental health and booze struggles spiralled.
Prince Harry spoke of his younger, partying days in a 2017 interview when he said he felt "directionless" and turned to alcohol, adding how he came close to a "breakdown".
His mental health had become so poor during his partying days, Prince Harry said he even considered turning his back on royal life years before eventually stepping down from The Firm as a married father-of-two.
