You may have thought Canadian born country star Shania Twain would have used her own love anthem, ‘From This Moment On,’ to be the first dance with her new husband at their wedding on Saturday, Jan. 1. Instead, she chose fellow Canadian crooner Michael Buble’s 'I'm Your Man' -- a song which was originally written by yet another Canadian, Leonard Cohen -- to be the song to which they floated across the dance floor.

PEOPLE reports other details about the wedding as well in a new issue. One of Twain's cousins officiated at the ceremony, and the color scheme was black and white -- the women wore black and the men wore white shirts, khaki pants and shorts. After the couple was pronounced husband and wife, the wedding party and guests sang the Beatles' 'All You Need Is Love.' In addition, Thiebaud presented his wife with a handmade book he did of words and photos "about his love for her.”

The wedding dinner included vegetarian comfort food and coconut cream cake, and all 40 guests arrived in Puerto Rico a week before the ceremony so they could enjoy scuba diving, snorkeling and sailing. Twain's 9-year-old son Eja walked her down the aisle, and Thiebaud's 9-year-old daughter Johanna was the ring bearer. One of Twain's bridesmaids says that the two children "are the best of friends. They've grown up together since birth.”

As was previously reported, Twain is currently starring in her own reality show, 'Why Not? With Shania Twain,' on Oprah Winfrey’s new OWN network. Hopefully, she’s working on some new music as well!
