The journalist girlfriend of French Socialist presidential candidate Francois Hollande tweeted Thursday she was furious to find herself on the front of the glossy Paris Match magazine she works for.

"What a shock to find yourself on the front page of your own paper. I am angry to see the use of photos without my agreement and without letting me know," Valerie Trierweiler posted to the popular micro-blogging site Twitter.

The elegant brunette who may soon be France's first lady – if as predicted by the polls Hollande wins the April-May vote – was pictured on the front of the weekly alongside her long-standing partner.

"Francois Hollande's charming asset. The story of how their love was born," ran the front-page headline, followed up inside by several pages of pictures and text about the couple.

Trierweiler has worked for Paris Match – which provides a mix of politics, celebrity news and reportage – since 1989, but last November agreed not to cover politics for the magazine during the presidential campaign.

Hollande is the former partner of Segolene Royal, who lost the presidential election in 2007 to the current French leader Nicolas Sarkozy. Hollande and Royal had four children together - but they split before the vote.
