Carl Philip, 41, is fourth in line to the throne. The couple tied the knot in 2015. The king is Sweden’s head of state, but his duties are ceremonial and he holds no political power.

In September, Sofia appeared in a documentary that aired on Sweden’s TV4 titled "Princess Sofia: Project Playground." In the special, the princess was asked whether she would consider stepping back as a senior member of the royal family, just like Britain’s Prince Harry and his wife, former American actress Meghan Markle.

"No. Not really," said Sofia, as quoted by Royal Central. "I think I have found such a fantastic balance, and I really see it as a positive that I have made it through these stormy years. It is such a huge advantage, in that we have the opportunity to stand a little in both worlds."
