Throwing her head back in a fit of giggles, Katherine Jenkins is clearly tickled over a royal joke.
And she wasn't the only female present pleased at a chance to meet Prince Charles at the opening of the Ryder Cup in Cardiff.
The wives and girlfriends of the players were full of smiles when they were introduced to the guest of honour at the star-studded inaugural concert in the Millennium Stadium.
Also on hand was Tiger Woods, a solo attendee following his recent divorce from Elin Nordegren.
The Prince also shared a laugh with local girl-turned-Hollywood star Catherine Zeta-Jones, who got a warm welcome as she spoke about her husband Michael Douglas' cancer battle.
