Blake Lively has made a return to Instagram in a seriously eerie way

She deleted all of her Instagram posts earlier this week.

But Blake Lively is already back on the social media platform - and she's brought a kind of eerie surprise with her. With her big return to Instagram, the mum-of-two posted the first look at her and Anna Kendrick's new movie, A Simple Favour.  The movie, based on a book by the same name, follows a woman named Emily Nelson who completely vanishes one day. https://www.instagram.com/p/BiRqOyxATfA/?taken-by=blakelively Anna Kendrick, who plays Emily's best friend, is heard saying in the voice over:

“I do consider Emily my best friend, she’s this wonderful, elegant person."

Amid scenes that show the lavish lifestyle of Lively's character, as well as her cuddling up to a handsome man, it's revealed that Emily went missing five days ago. Kendrick's character adds:

“I realized I don’t really know her as well as I thought I did. “Emily, if you’re out there, we’re all really worried.”

The former Gossip Girl actress sparked fans' curiosity earlier this week when she deleted all of her posts on Instagram and unfollowed everyone - except for 37 women named Emily Nelson. And the bio on her profile has been edited to simply read, "What happened to Emily?"
