Britain's Duchess of Cambridge was incredibly calm on her wedding day.
The 34-year-old royal - who tied the knot with Prince William, 33, on April 29, 2011 - was completely relaxed on her big day, according to her hairdresser Richard Ward.
He said: "I have some incredible memories of that day. When she walked back into Buckingham Palace and her hair was all still in place, I cannot tell you the relief we all felt!
"I've seen brides far more nervous than Catherine! She was fantastic - she kept us calm, not the other way round!"
And Richard praised the royal couple for being incredibly helpful.
He added to PEOPLE magazine: "I wanted to show Kate the back of her hair [getting ready at Clarence House for the evening party] and I was struggling to walk with this 500-year-old mirror.
"He just said, 'Let me give you a hand.' And I said, 'No, no, honestly.' But he took one end and I've got the other and we're shuffling along with this mirror - he's great, he really is. It was the most incredible experience and I'll never forget it."
Meanwhile, top stylist Nicky Clarke previously urged Duchess Catherine to cover up her "grey hair".
Nicky said: "Kate needs to get rid of her grey hair - it's not a good look. She does have amazing things done to her hair and it can look great, but unfortunately it's the case for women - all women - That until you're really old, you can't be seen have grey hairs.
"It's different for men. Men can go grey in their mid-50s and still be considered attractive. It's the whole silver fox thing. But it's not the same for women. Kate is such a style icon that even a few strands of grey would be a disaster, so I highly recommend that she cover it up. I hate grey hair."
