Shania Twain married Swiss business executive Frederic Thiebaud in Puerto Rico on New Year's Day and posted photos from the wedding on her website.
The 45-year-old Grammy-winning country singer, known for commercial hits such as "That Don't Impress Me Much" and "Still The One," said she wore Lorraine Schwartz jewelry, Calvin Klein shoes and bought her dress from a small boutique in Lausanne, Switzerland.
She and Thiebaud, 40, wed in front of 40 of their family members and closest friends and she was escorted down the aisle by her 9-year-old son, Eja.
Twain and Thiebaud have been dating for at least one year and announced their engagement in December, months after her divorce from ex-husband Robert "Mutt" Lange, Eja's father, was finalized. He had allegedly had an affair with Twain's best friend and Thiebaud's ex-wife, Marie-Anne Thiebaud.
Twain and Lange married in 1993, but separated in May 2008. Twain is set to release an autobiography in the spring of 2011, which will be her first book and will detail her "challenging and sometimes shockingly painful upbringing" in Canada. She is also set to have her own show on Oprah Winfrey's OWN network.
