Lourdes Leon is reportedly dating 'Homeland' star TimothÃ©e Chalamet.
The 16-year-old fashion designer - the eldest daughter of Madonna - met TimothÃ©e at the LaGuardia High School of Music and Art and Performing Arts in New York City where they are both studying and they have now made their relationship romantic.
A source told the New York Post newspaper: "It's common knowledge at the school that the pair are dating."
Lourdes - whose father is Madonna's ex-boyfriend Carlos Leon - is due to graduate from the prestigious school next year, while TimothÃ©e leaves this year.
The school was the inspiration behind the 1980 musical film 'Fame'.
TimothÃ©e is best known for playing the son of Vice President Walden on 'Homeland' although he has also appeared in TV series 'Royal Pains'.
Madonna - who also has son Rocco, 12, and adopted kids David, seven, and eight-year-old Mercy - previously revealed she gives Lourdes a lot of freedom but can be a strict parent when she needs to.
The 54-year-old pop superstar - who launched the Material Girl clothing line with Lourdes - said: "If she's a rebel I take her phone away ... But honestly I don't think I'm as tough as I should be. I think I need to be maybe tougher. It's hard though. Every day is a negotiation."
