Ronaldo, along with the likes of Sergio Ramos and Marcelo made surprise appearances on camera for the supporters - with one young fan particularly amazed by what he was seeing.
The video, posted to Real's social media feeds, sees two presenters video calling fans, asking to know a bit more about them ahead of the weekend final.
Off camera, the players watch the feed, waiting for their moment to shine.
One youngster, sat with his father, is asked by the presenter how Ronaldo celebrates his goals - the lad immediately imitates the star's spread legged, wide armed, open mouthed stance.
When a group of Real Madrid fans were invited to speak on webcam about their football club ahead of the Champions League final, they thought it would bring them little more than a few minutes of fame.
However, to their surprise it also gave them a chance to meet and greet some of the team's biggest stars, including Cristiano Ronaldo.
Also surprised are a group of schoolchildren - the video feed to the presenters seems to cut out, but when it returns a group of players are all sat ready to speak with their supporters.
