"A real honour to be part of such a truly magical moment in the most gorgeous setting for the incredibly awesome Kaley and Karl," she captioned the clip.

Cuoco echoed the sentiment with her own post, writing: "When @ginwigmore sings you down the aisle surrounded by every single person that you adore."

The actress also took to Wigmore's comments section to thank her for her part in the ceremony.

"You made everything extra special!! THANK YOU!" she wrote.

Kaley's sister Briana Cuoco officiated the wedding, and agreed with her sister, telling Wigmore, "It was magic!!!"
