Kate Middleton reacts to unexpected encounter during latest outing

• Kate Middleton's heart melts after sweet surprise
• Tiny Princess leaves the future queen in awe
  

A little princess stole Kate Middleton's show with her heartwarming gesture at the St. Patrick's Day Parade in Mons Barracks, Aldershot.

Princess Catherine, honourary Colonel of the Irish Guards, was caught on camera as she responded to a three-year-old daughter of a soldier serving in the Irish Guards on Tuesday, March 17, in an adorable moment.

The Princess of Wales laughed and held her hands as she shared an adorable moment with the tiny princess, who surprisingly giggled, swung from Kate’s arms and jumped on her legs.

Vienna, daughter of Lance Sergeant Mills, who led the drums and pipes during Tuesday’s parade, couldn’t contain her excitement as the Princess bent down to greet her.

 Kate asked the little one, “Are you excited?”

The Princess was also impressed by her “beautiful hair”.

The mother of three's show turned into fun-filled moment as another soldier’s daughter, three-year-old Mila, approached her.

Kate took her hands and complimented her on her green dress and bow, asking if “mummy” helped her with it.

The Princess of Wales dazzled in an emerald green coat and matching hat. She wore the Irish Guards’ gold shamrock brooch on her lapel, adding a spray of shamrocks for a festive finish.

The royal spellbound onlookers as she styled her hair in a braided updo, in an apparent nod to Irish heritage and Celtic folklore.

Kate burst into laughter when the Irish Guards cried three cheers of "Hip, hip, hooray" in her honour.

She also took a small sip of the drink as she no longer drinks much alcohol because of a previous cancer diagnosis.
