The lovely ladies were snapped in the charity's official tops - a grey limited edition tee designed by graduate Milly Wood, and a white 'Wear jeans, change lives' slogan number.
Beautiful Michelle looked the picture of elegance in both her tops, with her brunette locks loosely curled and her chocolate peepers defined with a slick of eyeliner.
The fantastic cause raises money to help transform the lives of children affected by genetic disorders, providing them with care and support.
This year, Jeans for Genes Day falls on Friday 20 September, when offices and schools will be encouraged to wear their jeans whilst helping to raise funds for the worthwhile cause.
And it's no surprise celebs have been queuing up to support the campaign, with Mel C and former MIC star Sophia Sassoon also rocking their denim with pride.
Both T-shirts come in sizes 8-20, with the limited edition grey tee costing £20 and the white tee costing £7.50. They're available to buy now from jeansforgenesday.org.
