Prince William and Kate Middleton will be visiting Norway and Sweden next year.

On Monday, Kensington Palace revealed some details about the Duke and Duchess of Cambridge's royal tour in 2018. The palace announced that Prince William and Middleton will be spending a couple of days in other countries in the first quarter of the year.

"The Duke and Duchess of Cambridge will visit Sweden and Norway from Tuesday 30th January to Friday 2nd February," the palace wrote on Twitter, adding the hashtags, "#RoyalVisitSweden" and "#RoyalVisitNorway."

According to Hello! magazine, the tour was announced earlier this year. Prince William and Middleton were supposed to visit Sweden, Norway and Finland in November, but they did not make it due to the Duchess' severe morning sickness. Middleton suffered from hyperemesis gravidarum during the first few months of her third pregnancy.

On the other hand, Prince William flew to Finland alone to mark the centenary of the country's independence. Middleton did not join him on the trip, but she did visit the Robin Hood Primary School in southwest London to celebrate the anniversary of the Royal Horticultural Society (RHS) Campaign for School Gardening.

During Prince William's visit to Finland, he handed the letter of his 4-year-old son Prince George to Santa. "I've seen you and I had to give you this letter," the Duke of Cambridge said.

Prince George asked for a police car for Christmas. Prince William also circled the option that the tot had been "nice" this year. "He hasn't written down many requests, so I think one request is probably ok," Prince William said with a laugh. "He's been a nice boy, a nice boy."

While Prince William was in Finland, Middleton enjoyed gardening with the kids. She was also spotted spending time with her mom, Carole Middleton. The mother and daughter duo were seen leaving the Kensington Palace with the pregnant royal at the wheel.

In related news, just like the Duke and Duchess of Cambridge, Prince Harry and Markle will be flying out of the country in 2018. Prince Harry and the "Suits" star are expected to fly to Australia months after their royal wedding for the Invictus Games.
