CRINGEWORTHY footage shows the moment Coldplay’s Chris Martin accidentally exposed a tech tycoon seemingly having an affair with a colleague.

Astronomer CEO Andy Byron and his alleged mistress can be seen rushing to shield their faces as they flashed up on a big screen draped in each other’s arms.

As a “kiss cam” camera panned onto married Byron and his HR chief Kristin Cabot at Wednesday night’s gig in Boston, Massachusetts, frontman Martin said: “Oh look at these two.”

But Byron – who had his arms wrapped around Cabot – swiftly let go of his grip and dived behind the barrier out of view as his shocked alleged lover hid her blushing face with her hands.

Laughter erupted among the thousands packed into Gillette Stadium as Viva la Vida singer Martin quipped: “Oh what… either they’re having an affair or they’re very shy.”

According to Byron’s LinkedIn, he has been CEO of software development company Astronomer – understood to be worth more than £1 billion – since July 2023.

Cabot, meanwhile, has been the firm’s Chief People Officer for nine months and boasts on her LinkedIn that she wins “trust with employees of all levels, from CEOs to managers to assistants”.

The mortifying footage from Wednesday night’s gig has gone viral on social media – having been shared thousands of times on X and TikTok.

Hundreds have accused Byron of cheating on his wife, and have shared support for her.

One social media user commented: “Sorry for the wife but glad they’re being exposed and embarrassed.”

Another wrote: “How utterly sad.”

A third said: “They are both incredibly stupid, sorry. Why would you go to a concert of all places if you are having an affair.”

Neither Byron or Cabot appear to have addressed affair allegations yet.

The Sun has approached Astronomer for comment.
