As we previously report, Lady Gaga was vibing along to her good friend Kendrick Lamar's set at this year's Pitchfork Music Festival. And now we have some footage of her doing so while he performs "ADHD." The Section.80 cut remains a fan favorite, especially the "fuck that!" chants on the hook.

You can watch the performance above and peep more footage at Pitchfork.tv.
