Prince Harry reportedly took Meghan Markle to Balmoral to help celebrate his 32nd birthday.

The loved-up royal is said to have taken his new girlfriend to grandmother Queen Elizabeth's Scottish estate six weeks ago, where she was introduced to his father, Prince Charles.

A source told The Sun newspaper: "Meghan's visit is significant. She met Charles and he was charmed by her. She was a real hit."

Although the queen was in residence, it's not thought she met Meghan as she was hosting UK Prime Minister Theresa May.

As well as staying at Balmoral, Meghan was also a guest at Harry's shooting party on the estate and she has also met his cousin Princess Eugenie.

And last month, the smitten pair visited Soho Farmhouse in the Cotswolds, England, before Harry flew to Toronto, Canada, to spend Halloween with Meghan.

The source continued: "Despite the fact that Harry and Meghan live on opposite sides of the Atlantic, they have managed to meet up fairly often.

"Harry as been paranoid at the relationship getting out before either of them knew if they wanted to continue.

"But it's moved very fast and they can't bear to be apart.

"They'll be meeting up again very soon."

While Meghan has gone down well with the royal family, her half sister recently hit out at her, saying Harry cannot trust the 'Suits' actress.

Samantha Grant - who shares the same father, Thomas Markle, as Meghan - said: "The royal family would be appalled by what she's done to her own family. The truth would kill her relationship with Prince Harry, he wouldn't want to date her any more because it puts her in a bad public light.

"I certainly don't think Harry or his family would want to associate with her afterwards."
