Richie teamed up with the actress and the reality TV star to bare all for an upcoming issue of Harper's Bazaar, with actress-turned-photographer de Cadenet taking the pictures.

Moore accompanied her photographer pal to the shoot on Tuesday (09Mar10) and was delighted when her friend let her step behind the camera to snap pictures of the naked women.

She described her day in a post on her Twitter.com page, writing, "Helping my pal Amanda de Cadenet (with) her photoshoot for Bazaar - all nudes showing all types of bodies love it! Especially cuz (because) I'm behind camera!"

Ritchie later took to her own Twitter.com page to talk about the shoot, adding, "Thank you Amanda de Cadenet & Mrs Kutcher (Moore) for such a wonderful, inspiring day. It was an honour being nude for you."
