Brazilian beauty queen Erika Canela, 26, claims she was sent 'offensive and insulting' messages when she ended her two-month relationship with the Portugal captain.
She says she received messages from the forward that called her a 'w****' and said he would 'ruin her life' but did not know if they were from him or someone else.
'I stopped eating, I couldn’t sleep and didn’t want to go out any more' she told the Sun on Sunday.
Her lawyers have launched a 'cease and desist' case against the striker and may seek damages over claims his actions were 'humiliating' and have 'profoundly affected her emotional state'.
The 26-year-old gained fame when she became the first black woman ever to win the 'Miss Bum Bum' title in 2016, a Brazilian contest that searches for the best bottom.
She shot to overnight fame in her native Brazil and won £18,000 and a string of lucrative modelling contracts.
Her new found fame gathered the attention of the former Manchester United player and she claims he invited her to his homes in Madrid and Lisbon to sleep with her.
Since becoming Miss Bum Bum she has starred on the cover of Playboy in Portugal, and posed naked for the magazine's Venezuelan edition.
