Now that's what you call a double-take! Zero Dark Thirty star Jessica Chastain was driving around Paris when she stumbled upon a picture of herself, and not just in a magazine on or on its cover — but plastered across a building!

The image in question is a huge billboard ad for Yves Saint Laurent's Manifesto perfume featuring a sultry-looking, glammed-up Chastain. The 35-year-old Oscar nominee was so giddy about her serendipitous encounter that she jumped out of her car and had a picture taken of herself posing in front of the ad.

Chastain— who has been seeing Gian Luca Passi, an Italian-born executive for French fashion brand Moncler — posted the adorable shot on her Facebook page on March 18. "Ok here's pic of me geeking out on my YSL campaign. I was in Paris for fashion week and look what I stumbled upon! It was as tall as a building," she wrote in her status update. "It was super embarrassing but I had to jump out of my car and seize the moment. I mean, how many times does a girl get a billboard over the Seine River!?!"

The snapshot has amassed more than 5, 500 "likes" so far.
