Elton is being sued by his ex-wife for £3 million, says the Sun's Bizarre column.
Renate Blauel filed documents with the High Court in London and claims that Elton's comments about their marriage in his autobiography broke the terms of an agreement they'd made after their split. It is also said to have triggered long-standing mental health issues.
A source reported that Elton is shocked and saddened by the claim, particularly as he has only had good things to say about her publicly, respects her, and ''always had a very pleasant relationship with Renate.''
The court papers state that the singer agreed to remove some passage before Me was published last year.
Elton is now married to David Furnish and they have two sons, but he has admitted he regrets causing ''sadness'' to the 67-year-old.
