Coleen, 28, will be debuting her S/S '14 range online tomorrow (9 April) but has shared a preview video to get us excited!
In the short clip, which was posted to YouTube, Coleen can be seen modelling gorgeous dresses, neon tops and stunning swimwear.
Coleen posted a link to the video on Twitter and told her followers: "So excited for my fashion show tomorrow, take a sneak peek..."
Mum-of-two Coleen first teamed up with Littlewoods back in 2010 and her work with the brand has gone from strength to strength.
Tomorrow, the star will be setting sail on a boat from Westminster in London to showcase her collection, with an on-board catwalk taking place in the afternoon.
The event will be streamed live on the Littlewoods website, so make sure you look out for it!
