Charlotte Gainsbourgmay be 45, but she certainly doesn't look it! She took to the French Riviera for a little R&R during Cannes, donning a black bikini.

I find Charlotte particularly fascinating; in part for her prolific nude scenes, of course, but also the upbringing that brought her to some of the most sexually explicit movies many of us have seen. She's the daughter of singers Serge Gainsbourg and Jane Berkin, and did her first nude scene in a short film when she was only 15and continued the tradition with her 18th in 1989:

And she's done no shortage of both French and American nude scenes since, many with taboo topics. There's The Cement Garden...

The terrifying Antichrist:

And, of course, Nymphomaniac:

With that body and that mindset, it seems unlikely this lovely woman will slow down anytime soon.
