Apparently, the Brazilian beauty, named only as Gabriela, 27, waved a poster of him at an international. According to reports, Ronaldo, 24, invited her to watch him play after meeting at a nightclub in Portugal.
Friends say the stunner then jetted to England to spend 7 days with the Manchester United star at his 4million-pound home, reports The Sun.
A friend of Gabriela - known as Gabi - said: "They've ended up dating. He's fascinated by her athletic body. She says he's attentive and romantic."
Another pal said: "They're a match made in heaven. Like Cristiano she never touches alcohol, and she's as fit as she is beautiful."
Gabi works at a gym in Sintra, near Lisbon.
