Her father Carlos Leon split from her mother Madonna in 1996, shortly after she was born.
But Lourdes Leon clearly bears no ill will towards the 47-year-old personal trainer.
The 16-year-old was seen attending Carlos' wedding to Zac Posen designer Betina Holte recently in Denmark.
The actor had a passionate affair with Madonna in the 1990s which resulted in their daughter Lourdes, 14, who he says is the love of his life.
Although their relationship did not last, Carlos said in an interview: 'I'm forever grateful to [Madonna]'.
The pair met in 1994 in New York City but split up seven months after the birth of their daughter in 1997.
'I have no regrets. I wouldn't change anything. I got the best thing out of that relationship, and that's my daughter. My daughter is everything to me', he added.
Speaking to People magazine, he admitted that he finds it difficult to be strict with his daughter.
'I'm a lenient dad. I'm very empathetic, and I'm good at listening to my daughter. I'm probably a bad dad when it comes to disciplining her', Carlos shared.
