As well as the daughter he shares with model Georgina, the Manchester United star also has son Cristiano Jnr, 11, and twins Eva and Mateo, four.
As well as newborn shots, both Georgina and Cristiano shared a photograph of the famous footballer doting on Alana while enjoying a rest on a sunlounger.
The birthday girl was also pictured in a rainbow coloured tutu while wearing a tiara and holding up a matching wand.
In one adorable shot, Alana cuddled up to the family’s pet pooch and Georgina also showed off Alana’s love of gaming in another snap.
Ronaldo’s oldest son Cristiano Jnr was born in the United States in 2010 but immediately taken back to Madrid to be raised in Spain. The identity of his mother is unknown.
In June 2017, the Real Madrid star then surprised fans with the news he’d welcomed twins Eva and Mateo through a surrogate.
Just one month later he and Georgina announced they were expecting their first child together. Georgina then gave birth to their daughter Alana on November 12, 2017.
Last month, Georgina revealed that she is pregnant with twins, sharing a sweet snap from a scan with her and Cristiano’s four kids to Instagram.
The beauty looked radiant as she gazed at the camera during her scan as the children beamed in the background, and captioned the post: ‘Impacientes ’ which translated means Impatient.
The professional football player also shared the happy news with fans on Instagram last month, and gushed their ‘hearts are full of love.’
Ronaldo, who will welcome his second and third child with Georgina wrote: ‘Delighted to announce we are expecting twins. Our hearts are full of love – we can’t wait to meet you.’

It comes after Georgina revealed she wants Cristiano to propose in a teaser for her new fly-on-the-wall Netflix series, Soy Georgina, which follows her at home, with her family, and at events with friends.
In the trailer she is badgered by pals about whether or not Cristiano will pop the question in the video, and responds: ‘It doesn’t depend on me… I wish,’ giving a knowing nod to her boyfriend.
She then says ‘Ojala’ – a Spanish term that loosely translates into ‘Should God will it’ and ‘Let’s hope so’.
Last month Georgina and Ronaldo relocated to the UK after the sports star returned to his old club Manchester United.
Georgina and footballer Cristiano famously met while she was working as a retail assistant in Madrid, as they caught eyes across the rails in Gucci in 2016.
Last year, she admitted that the meeting with the Juventus star saw her ‘fall in love at first sight’ amd claimed that the feeling was mutual.
She told Italy’s Elle magazine: ‘The first meeting with Ronaldo was at Gucci where I worked as a sales assistant. Days later we saw each other again at another brand’s event.
‘It was then we could talk in a relaxed atmosphere, outside of my work environment. It was love at first sight for both.’
Last year, Georgina sparked speculation that she’d tied the knot with her beau when she referred to him as her ‘husband’ in a gushing post celebrating her 26th birthday.
Sharing a snapshot of herself and Ronaldo posing with their children, Georgina wrote: ‘Happy 26 for me, very happy. I can’t ask life more. Just a lot of health for my family and me and to always enjoy them.
‘Thank you all for your congratulations, flowers and therefore love. And Thank you to my husband for giving me the best of life, our children. I love you.’
