The budding actress, who survived a suicide attempt last year (10), was linked to Rouve earlier this month (Feb11), but she is adamant their relationship is purely platonic.
Lenoir tells Britain's Guardian Weekend magazine, "(Rouve) is a good friend of mine. We are not dating. He is going to sue. Me? I don't care any more. I am over caring about that stuff."
She goes on to tell the publication she has been dating an unnamed doctor for two months, adding: "I met him through a friend. The normal way! Not in a club. (He's) a Jewish doctor who doesn't care about money. It is really different for me, because I love money, because I grew up with none, and because I have been supporting myself and my family since I was 17. But my boyfriend, he doesn't even have a big watch."
The 31-year-old beauty, who has enjoyed roles in films including Rush Hour 3 and After the Sunset, is said to be on the road to recovery with the help of her new boyfriend, filmmaker Jean Paul Rouve.
A source tells Britain's Daily Mirror, "Jean Paul makes her laugh and has given her a new lease of life."
Last May (10), the model was found unconscious in woodland in La Celle-Saint-Cloud, France, after allegedly ingesting a cocktail of drugs and alcohol.
Lenoir has a six-year-old son, Kelyan, with her former soccer star boyfriend Claude Makelele, and was previously romantically linked to rap mogul Russell Simmons.
