Kate Middleton has massively transformed from a commoner into a senior royal.

The Duke and Duchess of Cambridge just had a successful tour to Pakistan. According to Richard Price of The Sun, Middleton had a massive transformation from her overhauling her style to boosting her confidence.

He noted that onlookers might struggle to put a finger on what has changed for Middleton because “the real change is on the inside.”

“Like the finest of wines, she has taken years to mature to perfection, but the woman you see today has no peers on the global stage,” a well-placed royal source told Fabulous. "What people are seeing now is a confident, driven woman with a purpose. For the first time in her life Kate knows where she is going and has the self-belief to get there under her own steam.”

Middleton has received plenty of support from Prince William. After almost two decades Middleton remains to be an incredible figure but with more confidence.

“Back then she was full of self-doubt, despite all her assets. These days she’s a force to be reckoned with.”

Many have noticed that Middleton has become more confident over the years. According to an insider, she is cementing her role as the future queen. She is now more open and relaxed.

Body language Judi James also agreed that the duchess has become more confident as she takes a “more pivotal role” as the future queen. Meanwhile, Prince William is allowing his wife to take the lead as he takes the backseat.

Royal correspondent Emily Andrews also praised Middleton’s improvement. According to her, Prince William’s wife was more confident when she delivered her speech at the “Back To Nature” festival in Woking, Surrey.

“I was really struck by how much more confident Kate is at public speaking. Today’s engagement was very her, and she was in her relaxed element, but I remember when her elocution lessons left her with strangled vowels & v nervous delivery. Lovely job today,” Andrews wrote on Twitter while praising Middleton.
