The girls of Little Mix have urged fans to avoid buying unofficial tour books and annuals because they always contain incorrect details.

In the band's latest video tour diary, member Perrie Edwards explains that one annual in particular is full of false information and holds it up for the camera to show followers which book it is so they can avoid it.

"This is totally unofficial and this is why fans shouldn't buy unofficial stuff," Edwards declares, showing a copy of the Smash Hits Little Mix Annual 2013.

She was especially infuriated with it because a photograph of Little Mix was published, but one of the singers was missing and replaced with a different celebrity: "So this is all about Little Mix, but does that look like at any point that's us to you?"

Three of the 'DNA' beauties, namely Edwards, Jade Thirlwall and Leigh-Anne Pinnock, are pictured posing together but the fourth girl included is socialite Chloe Green, who they met at the BRIT Awards, and songstress Jesy Nelson is missing from the line up.

"That's me, Jade and Leigh with the owner of Topshop's daughter! That was at the Brits... They've put this picture in the Little Mix book," Edwards added.
