The former TOWIE star released Cross My Heart on Thursday (19 May) and has now been out and about signing copies of her book at a branch of WH Smith in Liverpool.
The 25-year-old wowed in a short white shirt-dress and rainbow-striped heels - but what really got heads turning was her bold hairstyle.
Ferne was looking cool with her hair in several plaits held tightly to her head, giving us serious '90s vibes.
The reality star looked delighted to be surrounded by copies of Cross My Heart, which Ferne previewed on Snapchat last week when she shared an extract reading: "As we go on in this book you will see a pattern: when I like someone they are automatically 'the one' and I become obsessed, which doesn't always work to my advantage."
And things are only going to get better for Ferne, as she's also revealed that she's jetting off to LA in July after landing a part in a film.
