Hollande 'can't control First Lady's thirst for revenge' against his ex

London, August 29 (ANI): France's First Lady Valerie Trierweiler is consumed by a 'thirst for revenge' against Francois Hollande's former partner, which the president is unable to contain, an author of a new book has claimed.

In the book, Entre Deux Feux (Between Two Fires), by investigative journalists Anne Rosencher and Anna Cabana, Trierweiler is portrayed as an emotional woman who relies on alcohol to steady herself for public appearances, the Daily Mail reported.

Trierweiler earned the nickname The Rottweiler earlier this year when she tweeted her support for a candidate running for election against Segolene Royal, Hollande's ex.

Royal, the mother of Hollande's four children, described the message as a 'poisonous stab in the back'.

But Trierweiler, a journalist with Paris Match magazine, is still looking for revenge after Royal warned her off the French president when she learned of their affair in 2005.

Royal, a senior Socialist Party politician at the time, allegedly called the reporter into her office and said: 'Everyone says you are Francois's mistress - it is unbearable for me.'

She then tried to get Trierweiler sacked from her job covering the Socialists, so the journalist would not have any excuse to approach Hollande.

But Trierweiler ignored the plea, and continued the affair until Hollande and Royal officially split after 30 years together in 2007.

The book also reveals the infamous tweet was sent from her Elysee Palace office after she argued with Hollande because he wanted to give Miss Royal a job in his government.

It even claims the journalist has 'banned' Hollande from making Royal a minister. (ANI)
