Georgina Rodriguez took the family on an outing to watch Cristiano Ronaldo Jr in action for Manchester United's academy.
The 11-year-old followed his father from Juventus to United this summer as Cristiano Ronaldo returned to Old Trafford in a sensational £20million transfer.
Cristiano Jr is the eldest of the Portuguese superstar's four children and Rodriguez took the family to watch him develop his skills in a fixture on Sunday.
It is not known which team he was playing for or what the result was, but Cristiano Jr had a strong contingent rooting for him from the touchline including siblings Eva, Mateo and Alana Martina.
Rodriguez posted a picture embracing the United States-born youngster and captioned it, "Supporting my big boy," with football and heart emojis.
Will we see Cristiano Ronaldo Jr line up for the Manchester United first team one day? Have your say in the comments.
The 27-year-old recently announced she is expecting twins with Ronaldo on Instagram, writing: "Delighted to announce we are expecting twins. Our hearts are full of love - we can't wait to meet you."
Ronaldo already has one pair of twins after Eva and Mateo were born via surrogacy in the USA in 2017.
Rodriguez, a Spanish model, gave birth to his fourth child, Alana Martina, later that year.
With the family set to grow even larger, Cristiano Jr is set to have more siblings to cheer him on.
It is believed he joined United's Under-12s in September after three years with the youth set-up at Juventus.
Cristiano Jr scored four goals on his debut for the Italian club and his grandmother, Dolores Aveiro, claims he is better at football than her son was as a child.
"At his age, he plays better than Ronaldo," she told ESPN of her grandson. "At that age, Ronaldo didn't have a coach but today Ronaldo is his son's teacher.
"He's already saying 'Dad, when we move to Lisbon I want to play for Sporting'.

Ronaldo opened up on his son's "passion" for football earlier this year but warned him it will take "a lot of dedication" to achieve his goals.
"I would love for him to be a footballer, because he feels passion for this sport," Ronaldo told DAZN. "He is a competitor and he hates losing."
"He's fast and he's driven. But this is nothing, it takes a lot of dedication."
