Romantic Ron handed his fiancee a £232,00five-carat diamond ring, reports Hello!.
And Portuguese daily Correio de Manha claims the pair will officially tie the knot after next year’s World Cup, depending on how Ronaldo’s Portugal get on.
Georgina, 23, is pregnant with the Real Madrid forward’s baby.
And her new dance teachers have started off on the wrong foot by accidentally revealing the sex of the couple’s unborn child.
The salsa pair confirmed suspicions Cristiano and his partner were expecting a girl in an Instagram gaffe.
Georgina posted a video of her enjoying her first class in a loose top which hid her baby bump and said: “Dancing makes your heart happy. Thanks to my teachers Basi and Deisy for giving me my first salsa lessons. I’m happy.”
Their reply, removed from social media after it was spotted by eagle-eyed fans, was: “A pleasure giving you salsa lessons.
“We’re very happy at how you did things in your first class. The little girl you’re carrying inside you is going to be a great dancer. Basi and Deisy."
Correio da Manha claimed in June shop worker-turned model Georgina was nearly five months pregnant with a girl.
The reports came a week after Cristiano, 31, posted a snap online showing him sat on a sofa with his left hand - and hers - placed on her stomach.
Cristiano’s girlfriend told glossy Spanish mag Hola in August how she was preparing for the birth of her first child - and the footballer’s fourth - on a strict Mediterranean diet.
But she made no reference to either her pregnancy or the sex of her unborn child.
Cristiano, dad to Cristiano Jr, seven, and surrogate twins Eva and Mateo who were born in June in a US hospital, claimed during a promotional interview in China earlier this year he wanted to take his tally of children to seven.
Half-Spanish, half-Argentinian Georgina, was working as a nanny in the UK less than 12 months before meeting her £230million footballer boyfriend in June last year at a Gucci store in Madrid.
She appeared to be enjoying every moment of her pregnancy - and looked a pro despite it being her first salsa class - as she moved effortlessly across Cristiano’s gym at his luxury home on the outskirts of Madrid in high heels, a short skirt and baggy T-shirt that disguised any sign she is just weeks away from giving birth.
