If you're one of Blake Lively's 20 million Instagram followers, you may have noticed that she wiped her entire account clean yesterday. (Spoiler alert: It was in promotion of her new movie, A Simple Favour.) Today, Lively resurfaced on Instagram to post the trailer for the new thriller film, which also stars Anna Kendrick as Lively's best friend.
As it turns out, Kendrick doesn't know Lively as much as she thinks she does—setting the scene for an intriguing mystery plot. Plus, if you pay attention to Lively's outfits, you'll notice a life-imitating-art moment: Her character wears a blazer, a button-down blouse, and a bow tie, just like Lively herself recently wore on the red carpet—and the outfit definitely has Gossip Girl vibes written all over it. Scroll down to watch the first teaser trailer for A Simple Favour, which comes out in theatres on September 14.
