Prince Harry and Meghan Markle, the Duchess of Sussex, await an addition to their family.
Meghan is pregnant with her second child, a spokesperson for the Duke and Duchess of Sussex confirmed to CNN on Sunday.
"We can confirm that Archie is going to be a big brother," said the spokesman.
"The Duke and Duchess of Sussex are delighted to be expecting their second child."
Their first child, Archie, is 19 months old.

The image, which appeared to be an illustration, was Archie's first glimpse since his first birthday in May.
