Move over Sherlock Holmes, because K-netizens have put on their sleuth hats.

With heartthrob Song Joong-ki married and expecting a child, naturally K-drama fans are wondering who the elusive Katy Louise Saunders is.

Previously, they found that she was an actress with a daughter from a previous relationship. This time, though, Internet sleuths have discovered one of her acting roles, and her co-star is none other than Hollywood giant George Clooney.
