It’s unclear why he is crying but he appears to be in pain as he holds his left eye during the celebrations.
As they walked onto the turf at the Principality Stadium, Ronaldo was talking to a friend while Rodriguez checked up on his young boy and comforted him.
The couple celebrated after an emotional game in Cardiff which saw Ronaldo score twice in the 4-1 victory.
Ronaldo has been dating Rodriguez since the end of 2016 after they are believed to have met in a VIP area of a Dolce & Gabbana event.
Ronaldo scored twice in their victory, with Casemiro and Marco Asensio also scoring for Los Blancos as they successfully defended the Champions League trophy.
The forward finished as the Champions League’s top scorer for the fifth season running and how now scored exactly 600 goals for his club and country.
He said: “We’re very happy to be the first team to win the Champions League in two consecutive years.
“I finished the season very well. It is another record, a record that these players deserve and we are delighted.”
