Even celebrities get starstruck!

On Wednesday,Jennifer Garnerhad “zero chill” when she received a surprise phone call from film legendJulie Andrews.

“@katiecouric asked @julieandrews to call me. It was a surprise. I’m sure you’ll be shocked to learn this, but I love her…#NextQuestionwithKatieCouric with Dame Andrews is out tomorrow. ♥️♥️ Happy Thanksgiving to all of us. #zerochill #thankyoukatie #♥️?♥️,” the actress wrote.

Alongside the note was the collage of 12 photos that show the emotional roller coaster Garner experienced while speaking with theSound of Musicicon.

In some photos, Garner hides her face in her shirt collar trying to conceal her excitement — while in others she shows off a wide smile while excitedly kicking her feet up in the air. In later photos, the actress seems to let go to her emotions and falls into her couch, slowly sliding onto the floor.

ThePeppermintstar also shared snippets of her conversation with Andrews, 84, on her Instagram story, including the moment when theMary Poppinsstar first called her.

“I wanted to tell you I’m a huge fan and love what you do,” Andrews told Garner, whose face was painted in disbelief.

“And Katie was just telling me that you were pretty admiring of me, too, so I thought, ‘Well let’s just have a chat,'” she added.
