Olympics 2012: Prince William and Kate Middleton hug in celebration
The smitten couple, who were sat with Wills' brother Prince Harry, 27, cheered and hugged from the crowd in celebration of Chris Hoy, Jason Kenny and Philip Hindes' gold medal achievement.
Earlier, Wills, 30, Kate, 30, and Harry had joined in with a Mexican wave, proving that they're willing to get involved with all the action of this year's games.
And earlier in the week, the young royals saw the Princes' cousin Zara Phillips and her take home a silver medal in the Equestrian Eventing.
They certainly struck lucky in the ticketing ballot...
