Angelina Jolie had travelled to the British capital to open a new centre in the London School of Economics.
The Centre for Women, Peace and Security focuses its attention on preventing sexual violence against women in war-time, an issue which Angelina aims to highlight and bring to public attention.
Angelina, who is said to be adding to the brood she shares with husband Brad Pitt, clasped her children's hands tightly as they made their way past photographers at the international airport in LA.
Six-year-old Vivienne and her twin brother Knox looked a little camera-shy, while their mum, wearing dark shades, a simple coat and tapered black trousers, took the obvious paparazzi interest in her stride.
We're sure the lovely Angelina was able to take the twin's minds off the unwelcome attention in no time!
