Tina revealed that she had first spotted her Giorgio Armani gown at a catwalk show in Beijing. "I thought, 'I gotta have that, even if I never wear it,'" she told HELLO!. "Then I thought, 'I know, that will be my wedding dress!'" The dress was embellished with Swarovski crystals.
In a further break from tradition, the 73-year-old superstar requested that all her female guests wear white, while the men wore black tie.
Though a practising Buddhist for many years, Tina reveals that she chose not to have a Buddhist wedding ceremony, opting instead for “the American tradition I grew up with, tailoring it a little bit to me".
The singer and Erwin have been together for 27 years, but she told HELLO! that she has finally reached a stage in her life that she calls her "Nirvana".
"It's that happiness that people talk about, when you wish for nothing, when you can finally take a deep breath and say, 'Everything is good,'" she said. "It's a wonderful place to be."
Media mogul Oprah Winfrey and singer Bryan Adams, who duetted with Tina on the rock song It's Only Love, were among the just over 200 guests and the celebrations lasted until 5am. The couple are currently honeymooning in Italy.
