Though it's the most prestigious film festival in the world, is currently undergoing in the south of France, this year Cannes has been making headlines not for the artistic and beautiful films being premiered there but rather for the way some of the stars walking the red carpet have looked - including Natalie Portman's Cannes dress.

Last week, Food World News reported that French Bond girl Sophie Marceau, a juror on this year's edition of the famous festival, had a major wardrobe malfunction as she was attending the premiere of "Mad Max: Fury Road" when she was oblivious to her underwear showing - and now something similar has happened to Natalie Portman's Cannes appearance!

According to The Huffington Post, Natalie Portman's Cannes appearance this year happened as she was promoting "A Tale of Love and Darkness," her latest film and directorial debut, a Hebew-language biopic of writer, journalist and pro-peace advocate in the Palestine-Israel conflict Amos Oz.

However, as Access Hollywood reports, it wasn't just the 33 year-old's considerable talent making headlines after the second of Natalie Portman's Cannes appearances, but rather her choice of outfit, as the Oscar winner wore a beaded and V-neck Rodarte with a sheer skirt that showed off her black underwear on the back!

The Daily Mail reports that the very first Natalie Portman Cannes appearance this year happened as she attended at the film's premiere last week, stunning the world in a beautiful black and white outfit from Dior, a remarkably conservative and classy account - but the way she dressed last Sunday was making headlines!

Portman's second dress seemed like a homage to the 20s decade, raciness and all, though with an asymmetric hemline that's apparently big this season, after major designers such as Chanel, Reem Acra and Anthony Vaccarello showed off this style in the catwalks.

In any case, as usual, Natalie Portman's Cannes appearance stunned everyone around!
