Natalie Portman's getting cheeky!
The actress was spotted at a photocall for her new directorial debut, "A Tale of Love and Darkness" at the 68th Annual Cannes Film Festival in Cannes, France on Sunday.
The Hebrew-language film -- which also stars the brunette beauty -- was adapted from the memoir of Amos Oz, an Israeli writer/journalist.
Portman stunned at the event wearing a sheer, black Rodarte dress complete with colorful sequins. The "Black Swan" actress finished her look with black strappy sandals and wore her hair pinned-back in a braid.
Natalie gave fans a real treat when she posed for photos from behind, and showed off her booty in the high-fashion number.
It's definitely a rare racy red carpet moment from the Oscar-winner -- and we're loving it!
