Spears angry with mom for writing book

London, Nov 12 Troubled pop star Britney Spears, who is working on a comeback, is upset with mother Lynne for writing a book about her and now wants pen her side of the story.

Lynne has signed a $1 million deal to pen the book on parenting. Spears wants to write her own memoir at the same time, contactmusic.com reports.

"She is trying to make a quick buck. She says she's not sure if she'll go through with it - but I can't really trust her," Spears reportedly told a friend.

Spears is trying to regain control over her life so that she can get custody of her children who now are with her ex-husband Kevin Federline.

She also has a new album out, "Blackout", as an attempt at a comeback.

Her lawyers are pleading with her to see a psychiatrist because they think she is "in denial" in the custody battle for her kids.

The lawyers are afraid she is not able to realise that she could lose her two sons in the custody battle with her ex Kevin Federline who now has temporary custody, thesun.co.uk reports.

"They fear that she isn't really worried about the battle. She believes the court is biased in Kevin's favour and is furious she has to undergo drug testing while he doesn't - so she won't play ball. But Britney won't listen and said she doesn't need a shrink," said a source.

This latest custody hearing heard Spears had missed drug tests as she doesn't like rising early.
