CHRIS Martin chuckled as he warned the crowd about using a kiss cam during a Coldplay performance.

Earlier this week, former tech CEO Andy Byron was spotted on the big screen embracing Kristin Cabot, the head of HR, at an event, leading Chris to ready the audience this time.

Both in the video are married with families – sparking rampant speculation of an affair – but neither of the humiliated pair has commented.

On Saturday night’s performance at the Camp Randall Stadium in Madison, Wisconsin, Chris said: “We’d like to say hello to some of you in the crowd.

“We’re gonna use our cameras and put some of you on the big screen.

“So please, if you haven’t done your make-up, do your make-up now.”

But the warning was clearly a nod to the alleged cheating exposed at the Gillete Stadium in Foxborough, Massachusetts earlier in the week.

Crowds members laughed and whooped at his words, revelling in the saga which has gripped the internet for the best part of a week.

The lead singer’s jibe was not the only reference to the scandal.

One concert-goer brandished a large sign declaring: “HE’S NOT MY CEO,” with an arrow pointing to the man next to her.

Since getting caught red-handed, Andy Byron has resigned as Astronomer’s CEO, according to an update from the company.

He had held the position since July 2023.

The company released a statement: “As we have previously affirmed, Astronomer upholds the values and culture that have been our foundation since inception. Our leaders are expected to exemplify excellence in both behavior and accountability, which was sadly not the case recently.

“Andy Byron has submitted his resignation, and the Board of Directors has agreed to it. The Board will initiate the search for our new Chief Executive, while Cofounder and Chief Product Officer Pete DeJoy will continue as the interim CEO.”

Panicked Byron and Cabot – who both have families of their own – were seen rushing for cover after being left red-faced in the packed stadium.

Their reaction to being filmed has caught the world’s attention – with millions now talking about the alleged affair.

And more footage captured from behind their seats, obtained by TMZ, shows the pair silhouetted by stage lights as Coldplay performed “Yellow”.

Chris Martin, Coldplay’s frontman, commented live on stage: “They’re either having an affair… or they’re very shy.”

Seconds later, Byron dropped his arm and ducked behind a barrier while Cabot covered her face.

As he caught view of himself, Byron appeared to say “f****** hell, it’s me”.

Martin added, laughing nervously: “Oh s***, I hope we didn’t do something bad.”

A night later, Martin cracked a joke with another couple on the kiss cam after accidentally catching the tech boss allegedly cheating with his HR chief.

The fan who captured the original kiss cam moment told The U.S. Sun she had no idea the couple were senior tech executives.

She said: “I just thought I caught an interesting reaction to the kiss cam and decided to post it. A part of me feels bad… but, play stupid games, win stupid prizes.”

Even longer footage has since dropped, showing the full reaction of panicked “mistress” Kristin Cabot.

Further revelations have since emerged claiming Cabot is still married to another powerful CEO.

Property records obtained by the Daily Mail from earlier this year list the couple as “husband and wife”.
