Just because Anna Kendrick starred alongside Ben Platt in Pitch Perfect doesn’t mean the 34-year-old actress has gotten used to his rising stardom.

On Sunday night, Kendrick attended Platt’s concert at Radio City Music Hall in New York City with her former co-star Brittany Snow. After the show, the A Simple Favor actress shared a heartfelt tribute on her personal Instagram account, where she gushed over Platt and his accomplishments.

The slideshow features a selfie of Kendrick and Platt, followed by a photo of the actor playing the piano during the concert.

She wrote, “Our baby is a superstar. I didn’t even make it through the first song without WEEPING.”

Kendrick went on to recall the moment she knew that Platt was destined for greatness. “2011, Table read for the first Pitch Perfect. After we finish, I make a dumb joke about how if there were a bunch of sequels (little did I know) there would be that one character that stayed on even when the rest of the cast wasn’t doing them anymore. I said, ‘Well the *character* would be Benji…but Ben is never gonna do it because that kid is gonna be a f***ing superstar,’” she continued, referring to Platt’s Pitch Perfect character.

She concluded the post with a full-circle moment, adding, “At this point, I hadn’t even heard him sing yet. And now, Ben is just fulfilling his destiny as the person who is too talented, too hard working, too joyful, too full of light to not become one of the most exciting and true artists on the damn planet. I’m so proud to know him and happy to have spent such a magical night watching him OWN Radio City Music Hall.”

Attaboy, Benji.
