In 2007, Prince William and Princess Kate had a brief breakup.

At a concert to honor Princess Diana in 2007, William and Harry introduced the acts.

Analysis reveals William's awkward dancing and Harry's expressionless reaction.

Kate was seated several rows back, likely due to the breakup.

An Analyst Chelsy noticed William's attention-seeking dance and reported it to Harry.

Harry reacted like a teenager embarrassed by his father's behavior.

William appeared to gloat to Kate about his independence without her.

William wasn't equipped for this kind of body language ritual.

This was likely a small swan song before William married Kate.
