Kathryn Mayorga alleges in court papers filed in Las Vegas that the incident happened back in June, 2009.
The complaint alleges that Mayorga was coerced into signing a nondisclosure agreement in 2010 in an out-of-court settlement in exchange for $375,000.
The footballer has denied the claims made by the German publication and said that they're "fake news".
"Ninety-nine percent of me is a good guy, I just don't know about the other 1%", he reportedly told her as he fell to his knees.
Ronaldo has yet to publicly respond this time.
These claims have been denied by Ronaldo's legal team as "blatantly illegal". "I wanted him to deal with it, to have to face me", she said.
The Las Vegas Metropolitan Police Department announced on Monday that it had reopened a criminal investigation into a sexual assault from the same date, though it did not specify the parties involved. "A medical exam was conducted", police confirmed in a statement released last night. She said she refused and it was then that Ronaldo assaulted her. She says she struggled to maintain relationships or hold down a job.
Der Spiegel alleged he raped someone a year ago as well but a rep for Ronaldo denied it vehemently.
When the New York Times first revealed in October previous year that former media mogul Weinstein had spent decades paying for the silence of women who accused him of sexual harassment - at the time at least eight settlements were known about - what followed was a deluge of new claims against him and six months later he had handed himself into New York police and was charged with rape and sexual abuse against two women.
The lawsuit said Mayorga reported the alleged assault to the Las Vegas police the same day and underwent an examination at a local hospital. (...) And she can't even get out of bed some days.
Ronaldo has been considered one of the world's best - if not the best - player for a decade. Another rich, powerful, seemingly untouchable man paying what at the time, on the verge of a move from Manchester United to Real Madrid, amounted to roughly a week's wages to potentially sensor some very serious accusations.
