George and Amal Clooney will be the Royal Baby Sponsors

Harry and Meghan became extremely close to the A-List tandem, which was the star guest of the royal wedding in May.

Amal, a human rights lawyer, has a longstanding friendship with the Duchess of Sussex.

Family members told DailyMail.com that the Hollywood star, Clooney, father of twins a year, considers herself almost a "shoo-in".

George would have "told a few people that he had a strong foreboding" that he would be part of the couples invited to play an important role in the child's life.

Hollywood couples took Meghan and Harry on a private jet to their luxury residence on Lake Como after their wedding in May, where they took an intensive parenting class taught by the Powerhouse couple.

George's cousin, Ben Breslin, told DailyMail.com that this 57-year-old man would make a "wonderful" godfather to the royal baby.

The new addition is scheduled for early 2019.

"I totally agree. He would make a wonderful godfather, he would make a wonderful, pretty much everything – he's a good guy, "said Breslin.

If the Clooneys are nominated godparents, this will represent a major break with tradition in that it will be the first time that a great Hollywood star is chosen.

Traditionally, the godfathers and godmothers are friends and relatives, but Prince Harry and Meghan were not retained at the Prince Louis baptism in July.

Prince Louis, the youngest son of Prince William and his wife Catherine, has six godparents: Nicholas Van Cutsem, Guy Pelly, Harry Aubrey-Fletcher, Lady Laura Meade, Hannah Gillingham and Lucy Middleton.

Van Cutstem, Aubey-Fletcher and Pelly are childhood friends of Prince William. Lady Laura Meade is the wife of James Meade, a close friend of William. Hannah Gillingham is Catherine's childhood friend, while Lucy Middleton is a cousin.

Louis' eldest brother, Prince George, has seven sponsors. Among them are Zara Tindall, cousin of Prince William, and William van Cutsem, Hugh Grosvenor, the Duke of Westminster, Oliver Baker and Emilia Jardine-Paterson. Jamie Lowther-Pinkerton, a former private secretary to William, and Julia Samuel, a good friend of his mother, Princess Diana, have completed the list.

Princess Charlotte has five godparents. They include more good friends of the couple – Sophie Carter, James Reade and Thomas van Straubenzee. Adam Middleton, Catherine's cousin, was also named godfather and William's cousin, Laura Fellowes, daughter of Princess Diana's sister, Lady Jane Fellowes, was named godmother.
