More than a year after splitting from her husband following his affair with her best friend, Shania Twain took to her official site to tell fans she’s doing great and to announce her new relationship, usmagazine.com reports.

On Friday, the country singer’s 44th birthday, she posted a personal letter and a 15-minute video travelogue of her most memorable moments from the past year.

“I feel very alive and well, ready to take on the gift of another year,” Twain wrote. The star split from her husband, Robert (Mutt) Lange in May 2008 after he had an affair with her longtime best friend, Marie-Anne Thiebaud.

“I consider myself on a journey of discovery and recovery,” she said of life post-split. “I don’t accept to be held down by the past, nor do I expect too much of the future.”

Who is accompanying Twain on that journey? Thiebaud’s ex-husband, Frederic Thiebaud, whom Twain calls “a dear friend and true gentleman.”

“We leaned on one another through the ups and downs, taking turns holding each other up. We’ve become stronger and closer through it all.”
