Prince Edward, 43, and his wife, Sophie, 42, are expecting baby number 2. The couple has a daughter, Lady Louise Windsor, born in November 2003. The new baby is expected in December.

A palace spokesperson told the Associated Press that "The Earl and the Countess [of Wessex] are both thrilled and excited. The countess will continue with engagements as normal and take doctors' advice."

Edward is the youngest son of Queen Elizabeth II and Prince Phillip, who are "delighted with the news" according to a Buckingham Palace statement. 

Sophie did have pregnancy problems in the past. In 2001, before getting pregnant with Louise, she suffered a life-threatening ectopic pregnancy according to the BBC. Hopefully, this pregnancy will be smooth sailing.
