Meghan Markle invited a lot of A-lister stars to her wedding to Prince Harry in May last year. The likes of George and Amal Clooney and Oprah Winfrey graced the special event, although the Duchess of Sussex reportedly didn't know them well. However, this seemed to create a new friendship that a royal expert claimed that these influential stars became her "outspoken supporters."

Royal biographer Andrew Morton told Vanity Fair that it was a smart move for the former actress to "befriend high-powered celebrities." Although the 38-year-old royal didn't know them well, these three publicly defended her against the criticisms.

"Meghan is smart, and she showed her purpose at her wedding by the people she invited," Morton said. "It was a clever move because they are the ones who have stood up for her when she has been attacked."

In February, George Clooney came on Meghan Markle's defense, saying that she was being "pursued and vilified" by the press. Oprah Winfrey, on the other hand, also showed her support to Prince Harry's wife in public several times this year, per Daily Mail Online. The media mogul even said that she is proud of the former Suits star for standing up for herself, saying what she wanted for her kid and family.

In addition, Amal Clooney reportedly started a close friendship with the Sussexes. They only live 30 minutes away from each other and enjoy lunches, dinner, and play dates with their kids together.

In fact, Grazia Daily reported that these two women gave a new meaning to the phrase "friends in high places. So, when did their friendship started?

A source revealed that Meghan Markle and Amal Clooney knew each other for a long while now. They even share a lot of the same interests. In fact, when the royal started living in London, she helped her settle into her new life. Their relationship was said to be a very natural one from the day they became friends.

There were also reports that Meghan Markle and Prince Harry went for a four-day trip to George and Amal Clooney's villa on Lake Como. Here, the Duke and Duchess of Sussex had the chance to meet the celebrity couple's twins, Ella and Alexander.

This only proved that Meghan Markle and Prince Harry had a close relationship with George and Amal Clooney. They enjoyed shooting hoops on the basketball pitch. Also, the villa hosted a gala dinner for a night, with reportedly about 15 guests.
