The footage, which has since gone viral, shows a man and a woman hugging at a Coldplay concert."Look at these two," Chris Martin said sweetly. When the two realized the entire stadium could see them, they tried in vain to hide."Either they're having an affair or they're shy," the singer joked.

Speculation about their identities is rife on social media. According to The Sun, the couple is reportedly Andy Byron, CEO of a tech company, and HR chief Kristin Cabot. Observant X-users claim the two are married, just not to each other.
