A source told the Mail on Sunday: "Lauryn has been wanting to do a book for some time. She has been talking about it and asking writers to pen it for her.
"As we know, she does not hold back when she wants to say something she wants out there, so it is likely to cause Kyle and Annie yet another headache.
"They have been trying to move on from all of this but with a book on its way, it will be pretty impossible. Lauryn doesn’t seem to want to live a quiet life."
