The Portugal star has been dating Rodriguez since 2016 and they have two children together. She is also the stepmother of his other three children.
In a game of Mr. and Mrs. on his new YouTube channel, Ronaldo referred to her as his 'wife'.
The two of them also appeared to both be wearing wedding rings in the video.
They have not previously gone public with any marriage ceremony.
The Portugal star has launched UR, a channel which aims to show a different side to him
Ronaldo is currently playing in Saudi Arabia with Al-Nassr but, despite being tipped to prolong his career for several more years, appears to be winding down his career.
The 39-year-old confirmed during Euro 2024 that it would be his last European Championship.
'It is without a doubt my last European Championship,' Ronaldo said, via Portuguese outlet O Jogo.
It is in that context that Ronaldo has launched his new YouTube channel, titled UR, promising to use it to show off a rarely-seen side to himself.
His content will delve into subjects away from his career on the pitch with numerous clips already filmed with his Rodriguez and their children.
The 39-year-old will also interview a host of mystery guests, it has been confirmed.
Ronaldo's channel was launched on Wednesday afternoon and features a sleek logo design - with the UR appearing like his CR initials followed by a play button.
In a one-minute taster, a laughing Ronaldo looked in high spirits.
'I have a big surprise for you, the new YouTube channel,' he said.
The channel's bio cleverly told viewers to 'SIUUUbscribe and join the CR7 family' in a nod to Ronaldo's now iconic goal celebration often repeated by crowds.
Nine videos have been uploaded to date. They include a 'Meet Georgina', a free-kick challenge with his son and a 'This or That' selection which sees Ronaldo choosing between iconic athletes such as Michael Jordan and Tiger Woods.
Shortly after, a Mr & Mrs quiz featuring Ronaldo and Georgina also went live.
