Cressida Bonas is the latest celebrity to snap a makeup-free selfie to help raise money for cancer research. Sporting a messy bun, Bonas looked just as stunning as she does with make up on.

Makeup-free selfies have so far helped raise 8 million Euros for the campaign, notes Mirror.

Other celebrities who bared all include Russell Brand’s girlfriend Jemima Khan, Helen Flagnan, Kym Marsh and Cheryl Cole. Actress Michelle Keegan also joined the campaign by posting a picture with the caption, “Mooorning! #nomakeupselfie #breastcancerawareness show your support text BEAT 70007 It’s so easy! Do your bit X.”

Bonas, 25, started dating Prince Harry in 2012 and the couple is becoming serious. According to the Daily Mail, Bonas and Prince Harry were recently spotted skiing in Kazakhstan.

Though they are going strong now, the couple broke up after photos circulated of Harry naked in Las Vegas with a bunch of other women. The couple managed to work things out and got back together.

Rumors of an engagement began when Bonas spent the weekend at the Queen’s estate with Harry. Neither has responded to the rumors.
