F1 driver launches nude calendar for charity

Valtteri Bottas has released a nude calendar for sale as part of his Movember charity push.

The Finn has been a free spirit since leaving Mercedes for Alfa Romeo ahead of last season and his social media presence has grown, with projects such as an 'Australian look' in an advertisement earlier this year.

But a picture of Bottas nude in a river last year sent social media into a frenzy - he even presented former teammate Lewis Hamilton with a large version of the picture - and he has now replicated that with a 13-picture calendar.

On sale for $20, $5 from each purchase of the 'Bottass' calendar will go to Prostate Cancer Research.

Bottas has raced with a moustache sticker on his crash helmet at recent races as he supports the Movember movement, which brings attention to prostate and testicular cancer, as well as men's mental health.
