London, June 6 : Soccer ace Cristiano Ronaldo's girlfriend has proved that she is committed to him by getting a tattoo of his initials.

Spanish model Nereida Gallardo had CR put on the inside of her wrist and plans to show it to the footballer next week.

"Nereida wants to prove she's committed to their future. She plans to show it to him next week. He doesn't know anything about it yet," the Sun quoted a friend, as saying.

Gallardo recently fuelled wedding rumours after she was spotted flashing a diamond ring on her engagement finger.

Sources said that the Man-U ace had told Nereida that they would tie the knot later this year if Portugal wins Euro 2008.
