PRINCE William and Kate Middleton may be the picture of elegance in public, but they do have some very sweet and affectionate nicknames for each other.

The royal couple – who share Prince George, Princess Charlotte and Prince Louis – are celebrating their 13th wedding anniversary this month, after meeting at university.

Royal editor Ingrid Seward told The Sun’s Royal Show that the Prince and Princess of Wales have some rather informal pet names for one another.

Speaking to The Sun’s Royal Correspondent Matt Wilkinson, she said: “Prince William was Big Willie, I think.

“Kate was Babykins, But people change their nicknames every time.”

Ingrid added that King Charles often refers to Queen Camilla as “darling” or “beloved.”

She added: “It’s really nice when he says ‘my beloved wife’, as he used to say with the Queen, ‘my beloved mother.’”

Meanwhile, the Duke and Duchess of Sussex, who often show displays of affection during public outings, also have some sweet names for one another.

Ingrid added: “We know that Harry is ‘H’, and we know that Meghan is ‘Meg’, but there could be lots of other things.”

Meghan also has an unusual collection of family nicknames, being called “Flower” by her mum, “Bean” by her dad and is called “Tungsten” by Charles because she’s tough.

The Queen was always known as “Lilibet” because she couldn’t say her name Elizabeth when she was young, and the name was used as inspiration for Meghan and Harry’s daughter Lilibet.

The royal expert praised Prince William and Kate for having a “great relationship”, with the future king supporting his wife.

She said: “William and Kate together they have a great relationship.

“They’re quite touchy-feely, but not overly touchy-feely like Meghan and Harry, they don’t cling to each other.

“But occasionally they do and they laugh together. They laugh together a lot.

“William is very, very supportive of his wife and I know that Carol Middleton has said that to friends, ‘he’s so supportive of my daughter’, and she’s very sort of proud of him.

“It’s that mutual support they have with each other.”

William first laid eyes on his future wife as they moved into the same halls of residence, St Salvator’s – known to students as Sally’s.

The pair were both studying History of Art, but William would later swap to Geography.

It wasn’t long before the Prince would start to notice “attractive brunette” student Kate, who was dubbed by fellow students to be the “the prettiest girl in Sally’s’ during Fresher’s Week.”

Kate was even given the nickname “Beautiful Kate” by fellow students, which certainly helped to get William’s attention.

Royal expert Katie Nicholl said: “She was initially more reserved than many of the other young women, but her natural beauty was apparent.”

The pair spent increasing time together, and it was Kate’s cheeky sense of humour that captured William’s attention.

William opened up about their initial bond in 2011, saying: “We just spent more time with each other, had a good giggle, had lots of fun and realised we shared the same interests and just had a really good time.

“She’s got a really naughty sense of humour, which kind of helps me because I’ve got a really dry sense of humour, so it was good fun, we had a really good laugh and then things happened.”

He added that he “knew there was something very special” about Kate, and “there was possibly something I wanted to explore there.”

The couple tied the knot in 2011 and went on to have their three kids together.
