Prince Harry has quit smoking for Meghan as they prepare to start a family after the royal wedding, it has been revealed.

According to the New York Daily News, the former Suits star has persuaded the royal to abandon his Malboro Lights and cut down on alcohol consumption ahead of trying for a baby.

'One of the reasons she got him to quit smoking is because smoking affects sperm production,' a source told the publication.

'It’s no secret among friends that they want to start a family immediately.'

Harry is also said to have lost 10lbs since he and Meghan announced their engagement in December, thanks to workouts at the exclusive KX private members health club in Chelsea where membership costs £575 a month.

The royal has been spotted there at 7am on an almost daily basis, 'getting his soldier body back'.

Meghan herself loves to keep fit and goes jogging to clear her head, as well as keeping up her yoga practice.

And it seems she's also keen for Harry to share her healthy eating practices as he's reportedly been working with Gabriela Peacock, the nutritional therapist at exclusive women’s club Grace Belgravia where Meghan is a member.

While the Prince is known for his love of KFC and Haribo, Meghan takes a rather healthier approach.

She previously told Good Housekeeping that her fridge staples are hummus, carrots, green juice, almond milk and chia seed pudding.

In December 2017, it was reported that Harry had stopped smoking at home at Nottingham Cottage in deference to Meghan.

‘Harry has promised no smoking at all at home. It’s not nice for Meghan as a non-smoker,’ a friend said at the time.

‘So there’s no more hanging out of the window for a quick puff.'
