Madonna's teenage daughter Lourdes is dating Homeland star Timothee Chalamet, according to a U.S. report.

The 16 year old is said to have struck up a romance with Chalamet, who plays Vice President William Walden's son Finn in the hit U.S. drama, after meeting him at the Fiorello H. LaGuardia High School of Music & Art and Performing Arts in New York, where they are both pupils.

A source tells New York Post gossip column Page Six, "It's common knowledge at the school that the pair are dating."
