The brunette beauty joined forces with Kara Tointon, Diana Vickers and Alexandra Burke in a feather-themed photoshoot for Asda's Tickled Pink campaign.
Michelle, who recently got engaged to TOWIE star Mark Wright, was an angelic vision as she posed for photographers while perched on a swing wearing a flowing white dress by Julien Macdonald with a string of pretty pink flowers in her hair.
"I want to encourage everyone to do their bit to help raise as much money as possible for Asda’s Tickled Pink campaign, which supports the fantastic and vital work of charities Breast Cancer Campaign and Breast Cancer Care," the small screen star said.
"I really enjoyed taking part in the campaign, which has already made a huge difference to women affected by breast cancer, and I hope that it inspires people across the UK to join in and buy a Tickled Pink product to help raise much-needed funds."
Michelle also showed her down-to-earth style by sporting a glamorous t-shirt in support of the campaign.
The photoshoot coincides with Breast Cancer Awareness Month. Tickled Pink was founded in 1996 by Asda with the aim to raise awareness of and money for the treatment of breast cancer in the UK.
