Tom and Giovanna Fletcher

The 31-year-old author is putting the finishing touches to her tome, 'Happy Mum, Happy Baby: My Adventures In Motherhood', which will document her experiences of family life with her McFly guitarist husband Tom Fletcher and their two sons, Buzz, two, and nine-month-old Buddy.

The cover has now been signed off by publisher Hodder & Stoughton General Division and Giovanna has shared it with over 777,000 followers on her Instagram account.

Along with an image of the cover, she wrote: "It is here!!! Super thrilled to share with you the cover of HAPPY MUM, HAPPY BABY! Aaaah! I really hope you like it! The book is available to pre-order now. Xxx (sic)"

Giovanna and Tom are always very open about their parenthood challenges and joys on their social media accounts and she has filmed magazine segments on TV show 'Lorraine' about motherhood.

The book - which will be released in February 2017 - will explore all of the ups and downs Giovanna has been through with Buzz and Buddy, leaving no subject off limits.

A synopsis for 'Happy Mum, Happy Baby: My Adventures In Motherhood' reads: "Being a mum is an incredible journey, a remarkable experience that changes how we look, how we feel, who we are. As mothers we are strong, protective, proud. We feel a love like no other. But being a parent can be hard too. It challenges us physically, mentally, emotionally. There are the days where just managing to fit a shower in amidst the endless feeding, entertaining young children and surviving on a lack of sleep feels like an achievement. With so many people ready to offer 'advice' on the best way to parent, it can feel like you are getting it all wrong. Since Giovanna and her husband Tom Fletcher have had their sons Buzz and Buddy, they have been sharing glimpses of their family life. With an infectiously positive outlook and happy take on all things mum-related, Giovanna has developed a following of fellow parents and mums-to-be. This is not a book about how to have the perfect family experience - Gi would be the first to admit she is winging it just as much as the rest of us - instead it is an honest, upbeat and incredibly personal account of her own experience of having a family."
