Blake Lively is out and about promoting her new role in A Simple Favor, and she stopped by The Tonight Show Starring Jimmy Fallon on Thursday. Blake hilariously explained her latest outfit mishap, which resulted in some serious miscommunication with a man on the red carpet. It turns out Blake didn't realize the outfit in question would go see-through under a camera flash, and it made her worry that everyone was staring at her chest. When a man on the red carpet crowd shouted "your tweets are amazing," she misheard him and assumed he was shouting another word with an entirely different meaning. It wasn't until the man started talking about her husband Ryan Reynolds's "tweets" that Blake realized her mistake. Watch the video above to see her explain the hilarious story in full.
