Former Corrie star Michelle was spotted dragging a suitcase down the street as she headed off to get ready for the glitzy event, held at the ME Hotel.
Michelle was all smiles as she embraced the warm summer weather with a floaty white dress, nipped in at the waist with a black belt.
The actress and budding fashionista wore her long brunette hair loose and kept things comfortable with a pair of nude flat sandals.
The new Lipsy Love Michelle Keegan autumn range features lots of gorgeous and sophisticated dresses, and the star has admitted to us that she is inspired by Victoria Beckham.
Speaking to Reveal yesterday, Michelle said: "Victoria Beckham is my inspiration, just for the fact she is very feminine yet clean with what she does.
"Her outfits are neat and tailored, and that's what I like in an outfit. I wish I had some style tips from Victoria Beckham!"
Michelle was joined at her launch last night by fiancé Mark Wright, however the couple are remaining tight-lipped about their forthcoming wedding.
"We have a venue and a date but because we've both been so busy, we haven't spoken about the other details yet," she said.
"But we want it to be a close wedding with family, because that's what it's all about... family."
