"I Do"

In an all-candlelight ceremony just after sundown, Urban and Kidman wed at Sydney, Australia's Cardinal Cerretti Memorial Chapel on St. Patrick's Estate at Manly. Guests at the black-tie event include Russell Crowe, Hugh Jackman, Naomi Watts and Rupert Murdoch, while Kidman's sister Antonia and Urban's brother Shane serve as maid of honor and best man. "It was the most emotional and beautiful ceremony," a guest tells PEOPLE. "Nicole looks ethereal with her veil floating, like a vision in white. Keith cried when he looked at her."

A Sobering Decision

With Kidman at his side, Urban admits himself into rehab. "One can never let one's guard down in recovery," he says in a written statement. "And I'm afraid I have." "He's a strong and amazing person," Urban's friend Anastasia Brown tells PEOPLE. "So he's dealing with this challenge just as he does with everything in life – with grace, strength and integrity." In January, he is released from rehab and returns to Kidman.

Aptly Titled

Urban's latest album, Love, Pain & the Whole Crazy Thing is released and the song "Once in a Lifetime" is nominated for a Grammy. Another track, "Got It Right This Time," features the following lyrics, presumably about Kidman: "She believes in me like I've been tryin' to do/I'm seein' things I've never seen before/Ever since she came into my life I've been a better man/Yeah, after all the crazy days I made it through."

Urban: "I Was Going to Lose it All"

As he begins another leg of his U.S. tour and releases his first greatest hits album, Urban opens up to PEOPLE about his road back after rehab and the devotion of his wife. "Nicole listened to her heart and did what she felt was the right thing to do," he says of Kidman who stuck by his side. "To see that kind of love in action, that's very moving and deeply inspiring and just makes me want to be a better man." In the new year, Kidman's rep announces that the couple is expecting their first child together.
