When will Princess Catherine be queen?

When will Princess Catherine be queen?

We don’t know for sure, but it’s likely to happen during our lives. See, King Charles is already 73 years old, so he won’t be able to rule for as long as Queen Elizabeth did. This means that Prince William and Princess Catherine could become king and queen consort in another ten or twenty years. You know, when their three kids, Prince George, 9, Princess Charlotte, 7, and Prince Lou wee, 4, are in their prime teenage years or early 20s.
