The world cheered on Monday as Meghan Markle, the Duchess of Sussex, and Prince Harry welcomed a new baby boy to the royal family.

As the son of the former actress and Los Angeles native, the newborn is the first interracial baby in the recent history of the British monarchy and will be a U.S. citizen. The baby weighs 7 pounds and 3 ounces, Buckingham Palace said in a statement.

The Queen, her husband the Duke of Edinburgh, and the entire royal family “have been informed and are delighted with the news,” the statement added. “The Duchess’s mother, Doria Ragland, who is overjoyed by the arrival of her first grandchild, is with Their Royal Highnesses at Frogmore Cottage.”

"Mother and baby are doing incredible well,” Prince Harry told reporters outside the couple’s estate in Windsor. “It has been the most amazing experience I could ever have possibly imagined.”

Prince Harry said the couple was still thinking about baby names and that the infant will be presented to the public later this week.

The newborn is now seventh in line to the British throne, behind Prince Charles, Prince William and his three children — Prince George, Princess Charlotte, and Prince Louis — and his father Prince Harry.

“Congratulations to the Duke and Duchess of Sussex on the arrival of their baby boy. Wishing you all the best at this happy time,” British Prime Minister Theresa May said in a tweet. The leader of the opposition Labour Party, Jeremy Corbyn, also offered congratulations and best wishes to the new parents.

"May God bless the new family with love, health and happiness," the Archbishop of Canterbury Justin Welby said. Welby officiated the couple's highly anticipated and watched wedding in May 2018.

From the U.S., former first lady Michelle Obama — a known close friend of the couple — cheered the news, tweeting “Barack and I are so thrilled for both of you and can't wait to meet him.”

Prince Harry and Markle thanked “members of the public for their shared excitement and support during this very special time” via an Instagram post.
