A “kiss cam” moment broadcast at a Coldplay concert struck a scandalous note when it apparently exposed a cheating tech tycoon and his head-of-HR mistress — as the band’s frontman, Chris Martin, mused that they must be “having an affair.”

The couple — identified as Astronomer CEO Andy Byron and the firm’s chief human resources officer, Kristin Cabot — scrambled to hide their faces when they were caught on the jumbotron canoodling at Gillette Stadium near Boston on Wednesday night.

As the camera panned toward them, Byron had his arms around Cabot’s chest, with her fingers intertwined with his.

They quickly realized they were on the screen prompting Cabot to fling her hands over her face and quickly turn around while Byron ducked down out of view.

At first, Martin thought the camera had captured a sweet moment. “Look at these two,” he said tenderly.

But their reaction quickly left him confused.

“Oh, what?” Martin can be heard saying on stage, according to a TikTok video. “Either they’re having an affair or they’re just very shy.”

“Holy sh-t. I hope we didn’t do something bad,” he said, according to additional footage taken right after.

The pair appear to work closely together at Astronomer, an AI and data company valued at about $1.2 billion. When Cabot was hired in November of last year, Byron gushed about her 20 years of HR experience and “exceptional leadership” skills.

Meanwhile, Cabot wrote on LinkedIn that her conversations with Byron before her hiring had “energized” her about the “opportunities” at the company. She also boasted that she wins “trust with employees of all levels, from CEOs to managers to assistants.”

Byron appears to be married to Megan Kerrigan Byron, while Cabot recently divorced her husband, Kenneth Thornby.

Cabot and Thornby filed for divorce in 2018 and the split was finalized in 2022, according to Massachusetts court records. It’s unclear if she has since remarried.

The former couple had at least one child, with Thornby being made to pay Cabot a lump child support payment.

Former employees of Byron were “laughing their ass off” about his alleged caught-on-camera affair, an ex-colleague said.

“The text groups and chains of former employees are like…everybody’s laughing their ass off and enjoying the hell out of what happened and him getting exposed,” the source said, adding that Byron was allegedly a “toxic” boss.

Observers Thursday were quick to point out she needs a lesson from her own HR handbook.

“Cost of a concert: Hotel $200, tickets $600, food/drinks $150, divorce attorney $50,000. Getting exposed by Coldplay having an affair with your co-worker: priceless,” wrote Instagram user Trustfundterry.

One X user claimed that Byron’s wife had dropped her married name from her Facebook profile, and didn’t restrict people from making comments.

The page was quickly bombarded with users reacting to the Coldplay concert clip before she deleted her profile.

A video uploaded on TikTok by user “Instaagraace” has received several million views and more than 1.3 million likes as of Thursday morning.

TikTok users pounced on the video as proof that the pair were having an affair.

“There is no plausible reason why they would act that way unless they were having an affair. Period. Can’t convince me otherwise,” one user wrote.

Another user mused: “If I saw my husband cuddled up with his mistress at the COLDPLAY CONCERT I would actually be sent to the psych ward.”

Astronomer did not immediately return a request for comment. Employees at the company’s New York office declined to speak on the record.

Byron and Cabot didn’t immediately return calls from The Post on Thursday.
