Prince William has just started his new job of being a rescue pilot. Reports claimed it was a big adjustment for the royal couple as the Duke of Cambridge is working in shifts that last up to 10 hours.

Because of the new job, Kate Middleton is reportedly under a lot of pressure as well, balancing household management, being a mother to a toddler and an infant, and attending to her official duties as a Duchess.

On top of the stresses of being a wife, a mother, and a royal, there's allegedly one other thing that's making Kate Middleton's days a lot heavier these days - the Duchess is purportedly jealous of a hot new doctor that Prince William is working with.

"Prince William completed his first flying rescue with his Kate Middleton-lookalike doctor, Gemma Mullen," Celeb Dirty Laundry wrote. "The undoubtedly tempted Duke of Cambridge and the sexy doc rushed to the aid of a man having a heart attack. William landed with the patient at the hospital, causing a gaggle of nurses to rush outside to wave at the royal.

"However, Prince William was busy checking his helicopter and trying to remain professional. The Duke gave a few waves, but an onlooker caught him checking his phone. No doubt, he was responding to Kate's messages."

Is Dr. Gemma Mullen making Kate Middleton jealous? And is the hot doctor aware that she is making the Duchess jealous and worried about her husband's loyalty?

Amid speculations, Daily Mail revealaed why Kate Middleton shouldn't be jealous of Dr. Gemma Mullen.

"I might point out that Dr Mullen has just married a handsome intensive care consultant called Tim Astles and returned from their dreamy honeymoon on the Amalfi Coast," Rachel Johnson wrote in an article for Daily Mail.

"Her husband used to work at Alder Hey Children's Hospital, and by the look of the couple's wedding pictures, he is the sort of doctor who makes even hardened, starched matrons with squeaky rubber-soled shoes secretly go weak at the knees."
