Danny Cipriani went topless and flaunted his tattooed arms in aid of Cancer Research UK's night-time walking marathon.
In one snap, Cipriani stands at the side showing the full extent of his tattoos with a pair of trainers slung over his shoulders, the Mirror reported.
In another shot, the rugby player, who is currently dating Brit model Kelly Brook, wears an unzipped grey hoodie while lifting his trainer clad foot in the air as if to kick something.
The rugged hunk dangles a pair of trainers around his neck while showing off his muscular chest, in another image.
