Little Mix found it therapeutic writing an autobiography.
The girl group - which includes Jesy Nelson, Perrie Edwards, Jade Thirlwall and Leigh-Anne Pinnock - enjoyed opening up with their new book 'Our World' despite it being ''really emotional'' to relive some parts of their past.
Jesy said: ''It's weird when you have to relive certain things. It can be really emotional to go back to a time which wasn't very nice for you.
''It was hard for all of us but at the same time it was like therapy.''
Whilst Jade added: ''It's quite a relief when it's out there.''
And the 'Shout Out To My Ex' hitmakers hope their book will give support to their fans who are dealing with similar issues.
Jesy told Maximum Pop: ''We just love the fact that our fans relate to us so much and that young girls will read this who are going through the same thing.
''I know that I've come out the other end a better person and that's what we try to do with our music so it's great to be able to do it in a book.''
Meanwhile, Little Mix previously revealed they are more like sisters than best friends.
In a sweet post shared to Twitter, Leigh-Anne wrote: ''A force to be reckoned with... for 5 years my girls and I have stuck together, been there for each other and grown into not only best friends but sisters.. that will always have each other's backs!
''We've been through break ups, we've been at our lowest but we have always helped each other and come out stronger on the other end! Call me the luckiest girl alive, because this is a dream I am living, but I get to live it with 3 of the most talented, special individuals alive. Now let's smash the s**t out of this #shoutoutomyex. (sic)''
