Cristiano Ronaldo is one happy dad.

On Friday, the soccer star took to Instagram to share a sweet family photo. In the snap, his girlfriend, Georgina Rodriguez, is holding his twins, Mateo and Eva, next to his oldest son, Cristiano Jr., who is reading a book. The family appears to be enjoying a peaceful day at the park. "Picture of the day," the Real Madrid player wrote in the caption.

According to Entertainment Tonight, Ronaldo and Rodriguez went public with their relationship in January when they graced the Best FIFA Football Awards red carpet as a couple. In June, Ronaldo welcomed his twin children, whom he described as "precious" in his announcement. The athlete added that he is "in love" with the twins, who were born to a surrogate mom in the United States.

A month later, in July, the pair announced they are pregnant with their first child together. When asked if he is happy with having a fourth child on the way, Ronaldo said, "Yes, very."

In August, Rodriguez opened up about her pregnancy and debuted her baby bump in a black mini-dress. "I am very family oriented and I love kids," she said.

Rodriguez also talked about her joy in being able to live her dream as a model and how she took care of herself while waiting for her baby. "I have worked with different luxury brands and with my contacts in the fashion industry, I have found something that I am passionate about," she said. "I like to take care of myself by doing sports and eating balanced meals. I try to eat natural products and avoid eating heavy meals."

According to Rodriguez, her motto is "mens sana in corpore sano," a Latin statement which means, "a healthy mind in a healthy body," Daily Mail noted. She practices this by surrounding herself with good people. "I like surrounding myself with those who inspire me to be a better person every day and bring me positive energy," Rodriguez said.

Rodriguez and Ronaldo are both excited for their upcoming bundle of joy who is due to arrive at the end of the month. "They are very happy with the arrival of the baby. Everyone adores Georgina and are satisfied with this relationship," a source said.
