Nadine, 52, was said to have ditched the 23-year-old after reports claimed she found out he’d dated a string of men before her.
Earlier this month, 44-year-old Rita Cumplido revealed Tiago had left her with an “enormous bruise” after striking her.
In an explosive interveiew in her native Brazil, the shop assistant claimed Tiago “beat her out of jealousy and transformed when he was drunk.”
Cumplido added: “He hit me so hard he left me with a black eye and an enormous bruise on my head.”
She claims to have reported the alleged act of domestic abuse to police and said a restraining order was issued against Tiago.
Despite all the controversy surrounding the relationship between Nadine and Tiago, Neymar is said to approve of the couple.
And reports in Brazil now claim Nadine has rented a luxury flat close to her Sao Paulo home for her lover.
Tiago was allegedly dating Neymar’s personal chef Mauro before beginning a relationship with Nadine.
It has also been reported that he was romantically involved with a famous Brazilian actor and stand-up comic called Carlinhos Maia.
Neymar had showed his support for the new couple after his mother posted a picture of them together to her social media pages.
Nadine posted a picture of herself cuddling up to Tiago alongside the caption: “The inexplicable cannot be explained, you live it…”
The Paris Saint-Germain commented: “Be happy mom – Love you”.
But O Dia reporter Fabia Oliveira claimed the 52-year-old had been urged by her family to end the brief fling.
Computer game fan Tiago was seen back with his family in Brazil after leaving Nadine’s mansion in April.
Last month, he posted a video of himself playing a game with his mother and sister to his Instagram page.
