The brand announced its partnership with the former Corrie actress this morning (20 March), debuting some stunning new snaps of the star.
Wearing pastel-coloured tops with denim shorts, Michelle can be seen showing off her faux glow.
'Garnier Ambre Solaire has been my favourite go-to self-tanner for years,' explains Michelle, who's currently starring in the BBC drama Ordinary Lies.
'To become a spokesmodel for Garnier Ambre Solaire is an honour. Garnier is a brand that I've grown up with and I've always admired the Garnier tag line of 'Take Care.'
'It's in line with my own values of taking care of myself with a healthy lifestyle inside and out with innovative skincare products,' she comments.
The star will appear on the products' packaging and in-store advertising from 1 May.
