Coldplay's Chris Martin accidentally exposes astronomer CEO Andy Byron having an affair with his HR chief Kristin Cabot.

The claim can be broken down into several components: 1) Chris Martin of Coldplay accidentally exposing a situation, 2) involving Astronomer CEO Andy Byron, 3) having an affair with his HR chief Kristin Cabot. Multiple credible news sources report that during a Coldplay concert at Gillette Stadium in Boston, the 'kiss cam' segment showed CEO Andy Byron and Kristin Cabot in a close embrace on the big screen.

Chris Martin commented on the moment, which led to viral attention and speculation about an affair. The footage shows them cuddling and attempting to shield their faces from the camera, which many interpreted as evidence of a secret relationship.

However, no direct confirmation or official statements have been made by the parties involved regarding the nature of their relationship. The reports consistently identify Kristin Cabot as the HR chief at Astronomer and Andy Byron as the CEO, confirming their professional roles. The term 'affair' is used widely in media coverage but remains an allegation based on the public display and context rather than confirmed facts.

There is no evidence from these sources that definitively proves an extramarital affair beyond the viral video and public reaction. Therefore, while the exposure by Chris Martin was accidental and did reveal a private moment between the two executives, labeling it conclusively as an affair is somewhat speculative without further confirmation.
