Prince Harry's girlfriend Cressida Bonas is the latest celebrity to post a make-up free selfie online to raise money for Cancer Research.
Bonas, 25, joined famous faces including Helen Flanagan, Cheryl Cole, Michelle Keegan and Jemima Khan in the campaign, which has so far raised more than £8 million for the charity.
Earlier this week, Bonas and the prince took a skiing holiday in Kazakhstan.
The couple were flown by government helicopter to Shymbulak, an exclusive resort owned by an oligarch with ties to the former Soviet dictatorship's political elite.
Campaigners criticised the couple for holidaying in a country whose regime is accused of serious human rights abuses.
It was announced last week that Bonas will accompany the prince to an event at the Queen's rooms in St James's Palace on 27 March, in one of their first official engagements as a couple.
At a function in the rooms held by the prince before Christmas, guests were told their wives, partners and girlfriends were welcome, and Bonas was said to fall into "that category".
However, Bonas faces competition for the prince's affections. In May a reality show will be launched in the US in which 12 US women compete for a date with an eligible young man they believe is Prince Harry, but is in fact Harry impersonator Matthew Hicks.
