The former Corrie actress, who left the soap at the end of May following a six year stint, has worked with designers to come up with an on-trend collection for young women.
Arriving at the ME hotel in central London, Michelle wore a short jumpsuit with an oversized leather jacket, accessorised with a deep tan.
The actress has just returned from a trip abroad with fiancé and former TOWIE star Mark Wright, where she no doubt took some time out to enjoy the sunshine.
Speaking of the collaboration Michelle said: 'I have been wearing Lipsy since my teens. I have always admired their collections over the years…I always feel great when I wear Lipsy.'
The star was joined by her husband-to-be Mark, 27, as well as other celeb supporters including The Saturday's Rochelle Humes.
Michelle recently left her role as Tina McIntyre in Coronation Street in order to pursue other projects, after spending six years on the soap.
Since 2007 the star has gone from completely unknown to one of the nation's best loved actresses, featuring highly in men's and women's mags alike too.
