The stars posed for the natural photoshoot with renowned photographer Rankin, which saw them leave their make-up bags at home to raise money for a worthy cause.
The new set of photos also features Olympian Denise Lewis, radio DJ Vanessa Feltz and actress Jodie Whitaker.
Michelle, who usually wows with her flawless beauty looks on our TV screens as Downton's Lady Mary and on the red carpet, explained why she decided to bare all for the campaign.
"It's such a simple way to get involved with raising money for Children in Need," said Michelle. "Ladies discard your mascara and join me and all out women in going BearFaced for the day."
The initiative encourages women to show off their natural beauty on Friday 8th November by swapping their usual make-up for a simple Pudsey Bear paw print face transfer instead. The transfers are available in most post offices throughout the UK.
Broadchurch actress Jodie Whitaker said of her part in the campaign, "BBC Children In Need carry out so much crucial work, so when I was asked to lend my support to their BearFaced Day campaign how could I say no?!"
The six celebrities join Laura Whitmore, Arlene Philips, Alex Jones, Sheridan Smith, Kimberley Walsh, Suki Waterhouse and Jo Wood, who announced their involvement in the BearFaced campaign in September.
2013 marks the 10th year that BBC Children in Need have worked with Boots UK, and the partnership has so far raised over £5million for children and young people across the UK.
With every £1 spent the No.7 skincare from Boots from 1-9 November, a five pence donation to BBC Children in Need will be made.
