James Corden famously told this Golden Globe award-winning actress that her name "is a mystery." Ronan admits there's a lot of vowels and that she's basically heard everything but the real pronunciation. Americans are prone to calling her SAY-oar-see but it's actually pronounced SUR-SHA.

The Irish actress is light-hearted about her name though and one time even wore a sign on The Ellen Degeneres Show that had her proper pronunciation written on it.
