Jewel and husband Ty Murray have split

Jewel says she and her husband, Ty Murray, are splitting after six years of marriage.

"My husband, friend and partner of 16 years and I have decided to get a divorce," she said in a message on her website Wednesday.

"Ty and I have always tried to live the most authentic life possible, and we wanted our separation as husband and wife to be nothing less loving than the way we came together," she added. "For some time we have been engaged in a private and difficult, but thoughtful and tender undoing of ourselves. Allowing ourselves the time and space to redefine what we are to each other with love rather than malice. "

Jewel, 40, and Murray, 44, married in 2008 after dating for a decade. They have one son, Kase, who turns 3 next week.

In a joint statement on the singer's website, she and Murray said they are committed to raising Kase together despite their split.

"Our dedication to our son is unwavering and we are both committed to being the best partners in raising our son," they said. "Due to the spirit in which we have gone about this separation, we trust we can remain dear friends who hold each other in high esteem, which is so important to us as parents -- as we wish only what is best for our son."

In April, when asked about her ideal date night with Murray, Jewel told CBS News, "You know what I love? Having a family has been amazing. Having a child -- I know that's a bit off the question -- but it's been a really amazing thing to be able to share a child with somebody."
