CNN: Harry and Meghan looking forward to seeing Archbishop Desmond Tutu

Royal fans can squeal with delight because baby Archie has finally made his debut on the Duke and Duchess of Sussex's tour of South Africa.

Harry and Meghan brought their four-month-old to meet beloved elder statesman Desmond Tutu and his wife Leah when the family visited their legacy foundation in Cape Town on Wednesday morning.

A royal source told CNN ahead of the tour that the Sussexes were hoping to include their son "at some point" but had been unable to say exactly when, as his age made a public appearance difficult to schedule.

Archie is thought to be youngest royal to go on an official tour, taking the title from his cousin Prince George who traveled with his parents to Australia in 2014 when he was just eight months old.

The Duke and Duchess of Sussex told Archbishop Desmond Tutu's daughter that they are excited to visit the beloved elder statesman and his wife Leah, according to the UK's PA Media news agency.

The royal couple will stop by their legacy foundation in Cape Town on Wednesday morning.

Harry and Meghan met Tutu's daughter, Thandeka Tutu-Gxashe, while attending a youth reception at the British High Commissioner's residence on Tuesday evening.

"They were saying that they were happy to be here and looking forward to meeting my father ... and hopefully they will have some time for conversation," Tutu-Gxashe told PA.

Tutu-Gxashe also said her 87-year-old father -- who has been ill recently -- was "doing OK."

"He is up and down," she added.
