Let’s skip right over that misspelling of a cappella on Yahoo! Style and focus on the misspelling of Charlotte Casiraghi’s name:
And then let’s focus on the assertion that she is an “actual Princess of Monaco.” No, even if the writer had managed to get her name right, she’d be wrong about that royal title. Charlotte Casiraghi may be eighth in line to the throne of Monaco, but she is not a princess; in fact, she has no royal title. None.
