Princess Charlotte and Pippa Middleton send royal fans wild with sweet interactions and 'matching outfits' at the Wimbledon final

Pippa Middleton was every inch the doting aunt as she joined the Princess of Wales and Princess Charlotte at Wimbledon this afternoon.

The mother-of-three, 40, shared several heartwarming interactions with her nine-year-old niece as they sat next to one another in the Royal Box for the Wimbledon's men's singles final.

Pippa looked effortlessly elegant in a slim-fitting red floral midi dress with ruffled tiers as she watched Carlos Alcaraz triumph over Novak Djokovic today. 

Meanwhile, Princess Charlotte matched her auntie Pippa in a navy-and-white polka dot dress from Guess with ruffled sleeves. 

At one point in the match, Charlotte was pictured whispering gleefully to her auntie and covering her mouth with a hand.

What's more, Pippa stepped up her auntie duties as her older sister the Princess of Wales made her way to the court to present the trophies.

During the standing ovation for the finalists, Pippa and Charlotte were seen beaming at one another from the front row of the Royal Box. 

As the players accepted their trophies, Princess Charlotte was seen leaning on the Royal Box's wooden frame as Pippa watched on and smiled.

Earlier in the day, the pair appeared in animated conversation during breaks between the nail-biting three-set match. 

The interactions were a hit with royal fans on X, formerly known as Twitter.

'Pippa is such a great role model,' one replied.

Another gushed: 'You can sense their closeness!'

A third said: 'I love that they are wearing dresses with a ruffle.'

Following Kate's cancer diagnosis earlier this year, the MailOnline reported Pippa Middleton and her brother James had been on hand to support the Prince and Princess of Wales and their young family. 

What's more, Charlotte appears to her younger brother's dramatic flair as she put on a scene-stealing display of emotions during the match.

The nine-year-old royal winced, cheered, and beamed, as she watched the players compete for the prestigious title.

Meanwhile, Pippa remained focussed on the game at hand - turning to check on Charlotte, who was sat in between her mother and aunt, at times. 

Despite her wearing a pair of £90 pink Ray Ban sunglasses, Charlotte's emotions throughout the game, from her jubilant grins to intrigued glances and awkward shudders, remained crystal clear.

Unlike her daughter, the Princess of Wales maintained a straight, concentrated expression as she watched the tense action. 

Before taking her seat in the Royal Box, Princess Charlotte appeared delighted to meet Emma Radacanu at Wimbledon today. 

The mother-daughter duo met with female tennis stars, including 21-year-old Emma Radacanu, who all presented Kate with a bouquet of flowers. 

Charlotte grinned from ear to ear as she met with the tennis star, who sadly saw her Wimbledon dream crushed on Centre Court by New Zealand qualifier Lulu Sun last week. 

The daughter of the Prince and Princess of Wales was nonetheless thrilled to meet the tennis star, and was photographed smiling ear to ear in her presence.
