The husband of a human resources executive who was caught cuddling up with her married boss at a Coldplay concert has broken his silence to confirm he and his wife had already separated when footage of her went viral.

Andrew Cabot, a businessman who has been married to ousted Astronomer executive Kristin Cabot, 52, for two years, was on a business trip to Japan in mid-July when his family was thrust into the spotlight.

Kristin was seen happily swaying in the arms of her boss, Andy Byron, 50, as they took in Coldplay tunes in the moments before they realized their love-in was being broadcast across the 66,000-seater Gillette stadium in Foxborough, Massachusetts.

Their reactions then became the stuff of memes, as Kristin raised her hands to her mouth before both she and Byron tried to duck out of the camera's view.

Andrew was said to have been 'blindsided' when he returned to find reporters outside his $2.2million waterfront home in Rye, New Hampshire that he shared with his wife and his two children.
