Elton, 73, tied the knot with German sound engineer Renate Blauel in Sydney, Australia, in 1984 and came out as gay in 1988 after their divorce, and Renate, 67, is now suing Elton after he wrote about their marriage in his autobiography.

Axar.az reports citing foreign media that according to The Sun newspaper's Bizarre column, Renate has filed documents with the High Court in London and is claiming that Elton's comments about her in the book broke the terms of an agreement they made after their split and triggered long-standing mental health issues.

The court papers state that Elton agreed to remove some passages before the publication of the book, 'Me', in October last year.

Elton went on to marry David Furnish in December 2014, nine years after their civil partnership ceremony, and the pair have two sons together but he has admitted to regretting at causing "sadness" to Renee.
