The Maleficent actress, who is now a UN ambassador and mother-of-six, claims the newspaper 'grossly violated' her privacy.
The star landed her damehood for campaigning against war zone sexual violence, but she has been working with the UN for over a decade.
Angela Lakor Atim, who survived years of abuse after being forced to marry a rebel soldier, hopes the Time To Act summit will help victims.
A-lister and Oscar-winning superstar Angelina Jolie has picked up yet another award - an honorary damehood for her campaigning work to which she dedicates her "lifetime".
Known for her roles in Hollywood roles Tomb Raider and Maleficent, she has been a leading lady cinema for more than a decade.
But Jolie, 39, is also a committed humanitarian and was described by US secretary of state John Kerry this week as a "fierce and fearless advocate" in this field.
Jolie is receiving an honorary damehood (DCMG) for services to UK foreign policy and the campaign to end war zone sexual violence.
She said: "To receive an honour related to foreign policy means a great deal to me, as it is what I wish to dedicate my working life to.
"Working on the Preventing Sexual Violence Initiative and with survivors of rape is an honour in itself.
"I know that succeeding in our goals will take a lifetime, and I am dedicated to it for all of mine".
David Cameron said sexual violence has "no place as a weapon of war in this world" as a global summit on the issue opened its doors.
The Prime Minister said: "This Government will always seek to protect the most vulnerable in society, both at home and abroad.
"Both in the Modern Slavery Bill and in our campaign against sexual violence in conflict we are protecting victims and punishing perpetrators - with tougher sentences for traffickers and ending impunity for soldiers who commit rape."
"Britain should not and will not tolerate trafficking," he added.
Foreign Secretary William Hague, who is co-chairing the largest summit on sexual violence in conflict with Angelina Jolie, wrote on Twitter:
Angelina Jolie has said a summit on sexual violence in conflict must send a message around the world that there is "no disgrace" in being a survivor and that "the shame is on the aggressor".
The Oscar-winning actress dedicated the four-day London event to an unnamed and "abandoned" victim of rape in Bosnia.
Foreign Secretary William Hague has announced the UK will pledge a further £6 million to support survivors of sexual violence in conflict.
Hague made the announcement as he opened the Time To Act summit with his co-chair Angelina Jolie.
Angelina Jolie has opened the largest summit on sexual violence in conflict, saying, "It is a myth that rape is an inevitable part of conflict."
"There is nothing inevitable about it. It is a weapon of war aimed at civilian," Jolie said as she stood next to the event's co-chair William Hague.
"It has nothing to do with sex - everything to do with power. It is done to torture and humiliate innocent people and often very young children," the actress added.
Angelina Jolie and William Hague have arrived to co-chair the largest ever summit on sexual violence in conflict.
Jolie said she was "so, so happy to be here" as she entered London's ExCel conference centre with the Foreign Secretary.
Labour leader Ed Miliband wrote on Twitter as a sexual violence in conflict summit was set to begin:
Today over 100 countries are gathering for the Global Summit to End Sexual Violence in conflict in London #timetoact
The scourge of sexual and gender-based violence in conflict is something we can and must tackle #timetoact
