Son of Nico, the singer of the group The Velvet Underground, Ari Boulogne, 60, has always claimed to be the son of Alain Delon. The actor has always denied en bloc, without ever agreeing to carry out a paternity test.

He decided to launch a legal procedure, in 2019, with the High Court of Orleans, having a residence in the Loiret. In September 2020, the French justice then declared itself incompetent to judge the request of Ari, because of the place of Swiss residence.
