King then staggers backwards in shock, tosses her purse on a nearby table and puts her hands on her chest.

"My bestie of 50 years is turning 70 so we gathered everyone that loved her to celebrate," Winfrey captioned the post. "Hard thing to surprise her, O the stories we have made up, the lies we have told to keep this a secret. Happy birthday @gayleking, sorry we almost gave you a heart attack."
