Around 1981, Paul gained publicity for becoming the lover of Princess Stéphanie of Monaco.

[2] In 1992, he joined the March F1 team as a pay driver, getting a ninth place at the Hungarian Grand Prix, but only qualifying 4 more times before he ran out of money and was replaced by Emanuele Naspetti.

Two years later he became a member of the uncompetitive Pacific Grand Prix team, where he only qualified for two races and was usually behind teammate Bertrand Gachot.

Thereafter he concentrated on GT racing, at the wheel of a Chrysler Viper GTS-R.

[11] In June 2024, Luana and Paul announced that they have separated in January and that they have filed for divorce.
