Anyone who follows Chelsea Handler on Instagram will know she's not afraid of a little overexposure - and now she's lending her assets to a very good cause.

The comedian fronts the new campaign for Stella McCartney's sweet pea-pink 'Stella' bra, proceeds from the sales of which will be donated to the Breast Cancer Research Foundation in the US, and the Linda McCartney Centre in Liverpool, UK, to support their work in providing the most advanced early detection programmes and treatments for patients with breast cancer.

It's a cause close to McCartney's heart; her mother, Linda, passed away in 1998 following a three-year battle with breast cancer. She was just 56.

'Breast cancer is the second most
common cancer in women all over the world and does not discriminate. While most
people are aware of this terrible disease, many also do not take the steps to regularly
get checked to detect it at its early stages,' said Stella. 'This set I designed is meant to
serve as a reminder to women to consider their health and visit their doctor
regularly. It not only looks and fits great, but is also an important healthy
reminder.'

Additionally, the designer has created the 'Louise Listening' post-double mastectomy bra, 100% of the proceeds form which will help benefit the Hello Beautiful Foundation, a UK-based organisation that aims to 'strip out the negative energy associated with cancer, and in turn highlight the beauty that can be found within this struggle.'

The 'Stella' bra for Breast Cancer Awareness, £42, is available now.
