Love is definitely in the air for royal couple Kate Middleton and Prince William even though they have been constantly plagued by marital troubles and divorce rumors. And while they are both busy attending several royal engagements, the Duke and Duchess of Cambridge also recently enjoyed some outdoor fun when they took turns climbing down a 12-meter wall in North Wales.

As Kate Middleton and husband Prince William took turns wall climbing and abseiling, they also give a rare glimpse of their married life and relationship. According to Daily Mirror, the 33-year-old Duchess teasingly asked her husband "how much do you love me?" when she held William's life in her hands as she dangled him over a 40-feet wall on an abseiling rope. Then, the cutest exchange between the royals happened.

"Are you holding me?!" Prince William nervously shouted up to his wife Kate Middleton. While the Duchess laughingly responded, "I've got you. I'm quite enjoying this actually. For once I'm in control."

Then Kate shouted down, "William - how much do you love me?"

After Prince William's turn, Kate Middleton took her turn. And when her husband had a go at climbing back up the wall, the Duchess' competitive spirit took over.

"Not that we're competitive but if he does that, then I'm having to do it too!" Middleton said.

After the royals' wall-climbing activities, Phil Blain, the 64-year-old instructor who helped them abseil, has only nice words for Kate Middleton.

"If that was Kate's first abseil she did fantastic," Bain said. "And that was probably the first time she's held the life of the heir to the throne - and her husband - in her hands."

the couple's abseiling activity took place when Kate Middleton and Prince William visited the Towers Residential Outdoor Education Centre in Capel Curig Wales. It was run by Wolverhapton Council, who has hosted several outdoor activities for children from their charities. But the trip seemed to have an effect on the Duchess as she admitted missing her life in Wales.

"I love it here," the Duchess, who lived in Anglesey for years when Prince William worked as a RAF search and rescue pilot, said. "I really miss being here, being outside and in the mountains."

Meanwhile, Kate Middleton and Prince William are also looking forward to spend their first Christmas as a family of four. The Duchess also added that her children, 2-year-old son George and 6-month-old daughter Charlotte, are doing really well.

"They are doing really well, thanks," the Duchess said, as per Daily Mail. "Charlotte is getting bigger and getting on well with her noisy big brother."

In other news, Kate Middleton is rumored to be hiding a baby bump as she and Prince William visited Wales on Nov. 20. Celeb Dirty Laundry claimed the casually dressed Duchess, who was wearing a gray wool coat, appeared to be hiding "just a hint of a baby bump." But it was not just a baby bump that was noticed, royal watchers also observed that the Duchess has returned to a healthy weight since her "skinny" appearance during the "Spectre" premiere in October.
