Prince Harry's Annoying Habit That Drives Meghan Markle Mad

Is there trouble in royal paradise?

They may have just rounded out a picture-perfect tour down under but for the Duke and Duchess of Sussex all may not be as rosy as it appears.

That's because Prince Harry has a rather annoying habit that drives his wife wild -- and not in a good way!

Eco-conscious Haz revealed in the new documentary Prince, Son and Heir: Charles at 70, that he makes sure he turns off all the lights at their Nottingham Cottage home in Kensington Palace. 

In fact, the 34-year-old royal admitted in the doco which aired in the UK on Thursday, that he's "obsessed" with ensuring he has as few lights on as possible at all times.

Harry explained that he inherited the “small habit” from his father Prince Charles, who is a longtime environmentalist.

“He’s a stickler for turning lights off,” Harry said in an interview with his big bro Will.

And that’s now something that I’m obsessed with as well.

Okayyyyyyy then.

Will's got the switch-turning-off-itch as well, saying, “I know, I’ve got serious OCD on light switches now, which is terrible.”

According to Harry, mum-to-be Meghan doesn't quite get the extent of his 'obsession,' which often leaves them both in the dark -- literally.

“... My wife certainly goes, ‘Well, why turn the lights off? You know, it’s dark.’ I go, ‘We only need one light, we don’t need like six.’"

Poor Megs, living in luxury but unable to see any of it. But her hubby's annoying habit does come from a good place, and it's even sweeter knowing that he picked it up from his ol' pa.

Speaking of Harry and Charles' father-son bond, it sounds like it was only made stronger after the young prince married his lady-love Meghan back on May 19.

When Meghan's father Thomas Markle was unable to attend the wedding after those dodgy staged pap pics surfaced, Harry turned to his own dad for help.

He remembered the moment he asked Charles to step in at the eleventh hour and walk his bride down the aisle at Windsor Chapel in the documentary.

I asked him to and I think he knew it was coming and he immediately said, ‘Yes, of course, I’ll do whatever Meghan needs and I’m here to support you,’

He added, “For him that’s a fantastic opportunity to step up and be that support, and you know he’s our father so of course he’s gonna be there for us.”

Charles and Meghan also reportedly have developed a bond, with the future king bestowing upon his new daughter-in-law a rather unusual but still endearing nickname.

Despite the light switch drama, it looks like it's all happy families for the British royals, and we wouldn't have it any other way.
