TECH CEO Andy Byron appeared to say “f****** hell, it’s me” after he was filmed cuddling on the jumbotron with HR chief Kristin Cabot.

The pair dived from the camera as they flashed up on a big screen in front of tens of thousands at a Coldplay gig in Boston.

Byron, who is married, quickly bent down to conceal his face by staring at the floor and took cover behind a barrier, while Cabot shielded her face with her hands and turned away from the audience.

Their reaction appeared to show guilt and has since gone viral online with speculation Cabot is the tech boss’ “mistress”.

The crowd, thousands strong at Gillette Stadium, erupted in laughter when Viva la Vida singer Martin joked, “Oh what… either they’re having an affair or they’re very shy.”

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

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

Per Byron’s LinkedIn, he has been serving as the CEO of Astronomer, a software development company valued at over $1.3 billion (£1 billion), since July 2023.

Cabot, meanwhile, has been the firm’s Chief People Officer for nine months.

The HR staffer – who has the second surname Thornby in brackets on her LinkedIn – boasts on her page that she wins “trust with employees of all levels, from CEOs to managers to assistants”.

It emerged last night that the Astronomer CEO had raved about the HR chief in a press release when she was recently hired.

Byron called Cabot a “proven leader” when she joined the company in November last year.

He gushed: “Kristin’s exceptional leadership and deep expertise in talent management, employee engagement, and scaling people strategies will be critical as we continue our rapid trajectory.”

Calbot released a similarly enthusiastic comment, saying she thought the “real magic happens when you align the people strategy with the business strategy.”

On her LinkedIn, she boasts: “I lead by example and win trust with employees of all levels, from CEOs to managers to assistants.”

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.
