Prince Harry describes 'fantastic' Christmas with Meghan Markle

Markle, 36, joined the royal family at Queen Elizabeth's estate, Sandringham.

Harry spoke about Markle during his special appearance today as guest editor of the BBC’s three-hour radio program, Radio 4.

"It was fantastic. She really enjoyed it," Harry, 33, said of Markle, 36. "The family loved having her there.”

Markle, a Los Angeles native, was the first fiancé to be invited by Queen Elizabeth to celebrate the Christmas holiday with the royal family at Sandringham, the queen’s estate.

Markle and Harry greeted the public after the royal family service Monday at St. Mary Magdalene Church. Markle, who looked a bit nervous, could be seen getting advice from Harry and William as they left the church.

Markle also mastered her first public curtsy as Queen Elizabeth departed.

Markle has said previously that Kate, 35, has been “wonderful” in providing her with guidance and making her feel welcome.

Markle and Harry announced their engagement in November. They plan to wed on May 19, 2018, at Windsor Castle.

Harry told the BBC that every family has its challenges and Markle has done an admirable job adapting to royal life so quickly.

"I think we've got one the biggest families I know and every family is complex," he said. "She has done an absolutely amazing job, just getting in there and it's the family, I suppose, that she's never had."

"I don't know about that," he said. "We didn't put the guest list together yet."

Harry added that he and Markle are looking forward to 2018 and predicted it will be a "fantastic year."

"As I said, we are really looking forward to the New Year and looking forward to 2018 because I'm determined to make sure that myself and the young generation and everybody else that this pendulum is going to swing," he said.
