Whose Sister Is Flashing Her Headlights in Cannes?

Actress starring in a movie premiering at the film fest rocks the French red carpet braless

That's one way to get attention at Cannes!

This up-and-coming actress showed off her goods while premiering her movie at the Cannes Film Festival in the south of France this week.

Think you know who hit the red carpet braless? (Hint: She's got famous siblings.)

It's Elizabeth Olsen, sans bra, at the premiere of Martha Marcy May Marlene.

And like the press-savvy younger sister she is, she rocked a dress from The Row, Mary Kate and Ashley Olsen's line for her big debut in France.

If you're going to get looked at and written about, you may as well give your sisters' fashion line some press too, right?

The 22-year-old, who was quite the media darling at Sundance in January, is quickly making a name for herself in Hollywood.

And it probably doesn't hurt that she's not shy about showing some skin, too!
