Swapping the runway for a red nose, supermodel Lara Stone will be lending her talents to the Comic Relief campaign.
Lara, 29, has got behind the lens once more to make some red nose day fun as part of a campaign to find Britain's funniest face.
The star has taken part in the humorous shoot to encourage the public to take the funniest snap they can while wearing the red nose, and to upload the result to Sainsbury's Facebook page.

The victor of the competition will win a VIP meet and greet with Jessie J, who is also shaving her head for the cause. A pop up booth with special guest celebrities will also be placed in selected stores.
"The Funny Faces competition is a fantastic way for everyone to get involved and support Comic Relief by doing something funny for money," said the Calvin Klein model.
"Just grab a Red Nose from Sainsbury's and strike a pose!"
As well as giving the charity her time and support, comedian husband David Walliams is a prolific supporter of the cause.
The Britain's Got Talent judge and philanthropist has swam the entire length of the Thames, the English Channel and the Strait of Gibraltar to raise money for the charity.
Attracting a-list attention, it seems that this year's campaign is going to be the biggest star-studded bash yet.
Kate Moss, Alexa Chung, Les Miserables star Eddie Redmayne and David Gandy have also posed for Comic Relief's t-shirt campaign, celebrating 25 years of the charity.
It's a little princess!
