Troops were drafted in to assist security guards at Games' venues in the capital, and The "Queen" star was full of praise for their efforts when she met them at an event in Wapping, reported Daily Express.
"As a resident, I have loved having the troops here. It has been great to see Tobacco Dock full of people and we have felt so close to what was happening in the Olympic park. It has been a very special event," she said.
The sporting extravaganza officially ended on Aug 12 with a star-studded concert, featuring stars including the Spice Girls, The Who and One Direction.
