Who? The guy from 'Titanic'?

Leonardo DiCaprio is a fantastic actor — and apparently quite the Renaissance painter, according to Fox News' Shepard Smith.

Smith made the gaffe Thursday while talking about scientists' ongoing search for the model of the Mona Lisa.

Of course, that famous portrait was painted by Leonardo da Vinci, who died about 500 years ago.
