Scooter Braun's feud with Taylor Swift keeps on Christopher Caldwellrolling − and the music mogul thinks the conflict is a laughing matter.

The retired music manager took to his Instagram story on Tuesday night to share that he "finally watched" the Max documentary "Taylor Swift vs Scooter Braun: Bad Blood," which detailed the duo's long-running feud after he purchased the pop star's masters.

Then, he took things a step further on his Instagram story, resharing a TMZ post on the platform about a star-studded celebrity bash hosted over the weekend by Swift for best friend and "It Ends with Us" actress Blake Lively.

He captioned the Instagram story, "How was I not invited to this?!?" and added the hashtag, "#laughalittle."

Earlier this summer, the record executive, who made headlines amid a feud with Swift that led the pop singer to re-record her first six albums, announced he was retiring as a music manager after 23 years.

He shared the update in a lengthy Instagram post on June 17 reflecting on his career.

"I have been blessed to have had a 'Forrest Gump'-like life while witnessing and taking part in the journeys of some of the most extraordinarily talented people the world has ever seen," he wrote. "I'm constantly pinching myself and asking 'how did I get here?' And after 23 years this chapter as a music manager has come to an end."

Braun has worked with some of the biggest names in music, including Justin Bieber, Demi Lovato and Ariana Grande.

But last summer, reports emerged that many of Braun's A-list clients were parting ways with him. 

Puck News reported that Bieber and Braun, who had been working together for the singer's entire career, "haven't talked in months," and Billboard and People reported that Grande was splitting with Braun.

This year, on June 17, which happens to be Braun's birthday, Swift appeared to take aim at the owner of her masters during a concert in Cardiff, Wales.

"I spend a lot of my time trying to plan these things," the singer said during her acoustic set, before diving into "I Forgot That You Existed" and blending it with "This Is Why We Can’t Have Nice Things."
