Real Madrid star Cristiano Ronaldo's girlfriend Georgina Rodriguez may be planning to have a 'super baby' with the 32-year-old footballer.

The 22-year-old model reportedly visited a clinic for detailed DNA tests to see if the couple are compatible to have a kid, reported The Sun.

Ronaldo was seen at the same clinic in the Spanish capital just days after her visit. The news comes amid rumours that she is pregnant after being pictured with a small tummy bump.

Recently, Ronaldo became dad to twins -- Mateo and Eva, with a surrogate mother in the US. He also has a six-year-old son Cristiano Ronaldo Jr.

"Georgina went to the clinic four months ago. It appears that they want to know what their baby may be like," a source was quoted as saying by the British tabloid.
