The couple revealed their happy news in an official statement on Dec. 11.
"Princess Sofia is well and the birth is expected at the turn of the month March-April 2021."
Their announcement was coupled with a lovely black-and-white photo that featured them lovingly embracing each other by the arms, which you can see above.
This is welcome news for the duke and duchess, who tested positive for COVID-19 in November. The couple spent their recovery quarantined with their children, and thankfully only experienced mild symptoms.
Carl Philip and Sofia's pregnancy is the latest in several other royal baby announcements so far this year. In September, Princess Eugenie happily revealed she and husband Jack Brooksbank were expecting their first child. The baby should be born in early 2021.
As mentioned, Carl Philip and Sofia also have two other children: Alexander, 4, and Prince Gabriel, 3. Carl Philip is fourth in line to the Swedish throne, meaning the baby will be seventh in line.
We can't wait for 2021 so we can welcome these little ones into the world!
