Kate Middleton and Princess Charlotte just had the most festive mother-daughter day ever

This is lovely.

Princess Charlotte might only be three years old, but she’s already one of the most popular members of the royal family, known for her signature sass.

And whether it’s debuting her royal wave to photographers on the way to meeting her newborn brother, attacking a balloon wall on camera or telling the press at Prince Louis’ christening that they weren’t invited, she never fails to be the centre of attention.

This - we hasten to add - is for all the right reasons.

This week, the miniature royal was back in the limelight, as she and Kate Middleton, Duchess of Cambridge, were seen having a mother-daughter day at the Royal Opera House, attending a special viewing of The Nutcracker.

But it wasn’t Charlotte’s sass that was getting her the attention. Instead it was her good manners, with the three-year-old patiently holding her mother’s hand as Kate talked and laughed with fellow guests.

Their attendance was unsurprising given that Kate is a known Nutcracker fan, attending last year’s show when she was pregnant with Prince Louis. Not to mention, Princess Charlotte is reportedly fond of dance, along with her brother Prince George.

‘She absolutely loves it,’ Kate explained of her daughter to Tamara Rojo, the director of the English National Ballet, going on to explain how her children get their fondness for dance from their late grandmother.

‘She loved dancing, she was a fantastic dancer,’ Prince William went on to explain about his mother, Princess Diana, with a passion for dance clearly running in the family. ‘We've been going through her music collection recently and there's some quite eclectic stuff in there. She was elated by the skill.’

This is making us feel so festive.

Mother-daughter goals to the max.
