The Juventus star’s legal team discuss his account of a night with Kathryn Mayorga, 34, in Las Vegas in the emails.
They centre on a questionnaire Ronaldo, 33, is said to have filled in for his lawyers after having sex with Ms Mayorga in a hotel in June 2009.
The former Man United ace appeared to admit that she said “no and stop several times”when he gave answers in September that year, German magazine Der Spiegel claims.
But a second version of the document with different answers was reportedly produced in December 2009.
In it, Ronaldo denies that Ms Mayorga said anything to suggest that she did not consent to the sex.
The football superstar has publicly denied all wrongdoing and stated that a hacker had fabricated the paperwork to make him look guilty.
But Der Spiegel suggested that the original questionnaire “cannot have been a falsified document” as they printed new emails yesterday.
They said the messages show Ronaldo’s lawyers talking about the document and using the same phrases he used in his answers.
One asks how to translate the Portugese phrase “toca-me ao bicho”, which means “she touched my d**k”.
Ronaldo, who recently visited London with girlfriend Georgina Rodriguez, 23, denies attacking Ms Mayorga and maintains sex was consensual.
