Is Kate Middleton feeling a little threatened? That's the rumor as the Duchess is apparently very jealous of her new rival, Princess Madeleine of Sweden and her rising popularity in the media.

Kate Middleton News 2015: Queen Elizabeth Reportedly Thinks The Duchess Isn't 'Natural' Enough

According to Celebrity Dirty Laundry on Wednesday, Prince William's wife is none too happy over the fact that the spotlight is now being turned on Princess Madeleine, who is working her charm in becoming the most popular royal figure in the entertainment world.

The site says that she and her husband, British-born banker Chris O'Neill decided to publicly live-stream their three-month-old daughter Leonore's baptism on Swedish national television. Sources say the little princess quickly "stole the show" and Swedish hearts during the livestreaming of the event.

Duchess Catherine and the British Royal Family meanwhile decided not to broadcast 5-month-old Princess Charlotte's baptism back in July and in fact has been rarely seen in public ever since she was born last May.

To make matter worse, the Duchess and her husband Prince William even refused to attend Princess Madeleine's star-studded wedding back in June of 2013, as Queen Elizabeth sent the Earl and Countess of Essex as her replacement. Sources say it's simply because she is envious when it comes to the Swedish princess.

The gossip blog also says that "Duchess Kate is ridiculously jealous that Princess Madeleine is a Royal power-player and she's not - and may have to wait two decades before she is even close."

So far, a rep for Kensington Palace has not made any comments about the report. Keep up with Enstars for all the latest news on Kate Middleton, Prince William and all of your favorite royal celebrity news right here.
