Former TOWIE star Ferne was all smiles as she arrived at the event, which has been held at London's Ginger Martini to celebrate the publication of Cross My Heart.
Ferne, 25, turned heads in a show-stopping monochrome jumpsuit, which featured a bold star print from top to bottom, and she teamed it with a seriously high pair of black sandals.
The Essex gal completed her look with a statement choker, a slick of bright pink lipstick and a huge grin!
Cross My Heart goes on sale tomorrow (19 May) and Ferne has promised fans lots of gossip and heartfelt tales about her life, from birth to where she is today.
In a sneak peek of her autobiography, Ferne recently revealed that she falls in love too easily.
In a photo shared to Snapchat of a highlighted extract, a page from her book read: "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."
It is a hugely exciting time for Ferne, as she recently revealed she is also flying to Los Angeles in July after confirming a role in a film.
The I'm A Celebrity...Get Me Out Of Here! star is turning her hand to acting and, on Tuesday, told This Morning viewers: "It almost seems too good to be true… so we'll see."
She then joked: "It's absolutely not an adult movie!"
Have a great night, Ferne!
