My theory on what happened
Blake Lively's career is very stagnant I mean this Baldoni movie is basically a B-Movie. So she got together with her publicists manager, maybe even her husband to throw this BS sexual harassement accusation at Baldoni inorder to promote herself and make herself relevant in hollywood again.
Now I was againt Baldoni in the beginning and supported her because the guy has the most punchable face with gay lips. But after the evidence started coming out and the clip of their dancing scene we can clearly see she is lying.
I hope Baldoni wins his lawsuit and Blake goes back to being a stayhome mom.
