He is known for his relentless hunger for scoring, but off the pitch Cristiano Ronaldo is a little more generous.

During a recent pitstop in Las Vegas, the Real Madrid star showed off his chivalrous side by tracking down an American fan that had lost her phone.

When the pair finally came face-to-face, Austin Woolstenhulme says he made the meeting even more memorable by treating her and her pals to a night out in Sin City.

"Bad news is I lost my phone two days ago. Good news is Cristiano Ronaldo found it. Better news is he took us to dinner last night," she captioned an Instagram snap of her and the 30-year-old ace.

She also jumped on Twitter show the group on their night in the US party capital.

Woolstenhulme was later tagged in a Facebook picture that suggests that the gang may have continued the festivities back in the player's suite.

"Hanging out in Cristiano Ronaldo's suite, selfie in the bathroom off course. A night to remember!"

Hours later Cristiano Ronaldo was in Tokyo promoting an electric muscle stimulation machine dubbed the new 'Body Revolution Project'. The video played on overhead screens at the press event showed CR7 with the electric toner strapped to his well-toned torso.
