Now it appears Meghan's healthy way of life has rubbed off on Harry, who has vowed to give up smoking for his future bride.
A friend of the Prince told DailyMail, 'Harry has promised no smoking at home. It's not nice for Meghan as a non-smoker.
'So there's no more hanging out the window for a quick puff. Harry has quit for Meghan.'
Harry reportedly started smoking in his late teens and again when he joined the Army, and is now limiting himself to the odd social cigarette.
Meghan previously told Women's Health that she credits running, yoga and her healthy diet to maintaining her slim figure. Meghan also told the publication she prefers to have a green juice over coffee for her morning boost.
