Oh, snap!

Astronomer CEO Andy Byron and his HR chief Kristin Cabot were caught smooching at Wednesday’s Coldplay concert before their alleged affair was exposed on the event’s “kiss cam,” a new video shows.

The two-timing co-workers huddled close as they repeatedly locked lips and embraced while appearing to belt the lyrics to Coldplay’s “Yellow” to each other as it played during the concert, according to footage obtained by TMZ Friday.

The silhouetted secret lovers — both of whom have families — were also seen laughing and swaying arm-in-arm to the hit song as the massive crowd lit up Gillette Stadium with their cellphones.

The steamy office tryst was later put on blast when the jumbotron suddenly panned to them — prompting the cuddling pair to awkwardly duck out of view as they scrambled to hide their faces.

“Oh, what?” lead singer Chris Martin said after catching the embarrassing viral moment.

“Either they’re having an affair or they’re just very shy.”

The tech tycoon and chief people officer of the AI-centric New York firm have since been placed on leave after the caught-on-camera faux pas erupted into a social media frenzy, sources told Axios.

Byron is currently stalling his resignation as he negotiates an exit package and salary, according to the report.

The company announced Friday that it had launched an investigation into the illicit fling.

“Astronomers are committed to the values and culture that have guided us since our founding,” the company said in a statement.

“Our leaders are expected to set the standard in both conduct and accountability. The Board of Directors has initiated a formal investigation into this matter and we will have additional details to share very shortly.”

Neither Byron nor Cabot has spoken out yet about the salacious scandal.
