What began as a feel-good concert gimmick quickly spiraled into a PR nightmare for a billionaire tech boss—captured live for thousands to see and millions more to share.

Coldplay’s Wednesday night show at Gillette Stadium took an unexpected turn when frontman Chris Martin kicked off the classic kiss cam segment to fire up the crowd. But when the camera zoomed in on Astronomer CEO Andy Byron and his Chief People Officer Kristin Cabot, the mood flipped in an instant—from fun to full-blown scandal.

The audience gasped as the screen lit up with the image of Byron, a married man, cozied up with Cabot in a moment that looked far too intimate for colleagues. His arm was around her; she leaned in close, all smiles—until they realized they were being broadcast. Then chaos.

Byron yanked his arm back and ducked behind a railing like someone caught in the act. Cabot froze, hands over her face, clearly shaken. The crowd murmured. The cameras lingered. And then Chris Martin delivered a perfectly timed zinger that sent shockwaves through the stadium and, soon after, the internet.
