"She stood for the whole ceremony and then walked through a room of 600 to 800, meeting people. She's got some incredible stamina," she said.

"She had an amazing time in Ireland and it was a great thing to have her come and for Ireland to move on," Ali said.

Ali stated she was looking forward to meeting Aung San Suu Kyi when she visits Ireland on JUne 18th and Bono presents her with the Amnesty International Ambassador of Conscience award.

"It's such an incredible thing to have her come to Ireland. It's a huge honour for us to have her in the country," she said.

Ali refused to comment on Facebook and how she and Bono feel about the company which they own major shares in "I'm going to leave that one," she said. "But I still have a huge amount of faith in Facebook and the markets are all over the place anyway.”

"We'll see how it rides out but it's a long-term thing, it's not a short-term thing," she said.
