and her husband Ty Murray, who announced their split
on Wednesday, are working on an amicable divorce.
The singer shared a photo on Instagram
on Saturday that showed her and Murray celebrating Independence Day with their son
, Kase, who turns 3 in a few days.
"Happy fourth everyone!" she wrote. "@typbr Kase & I enjoyed the parade here in CO."
Jewel, 40, who married
the professional bull rider in 2008, wrote in a blog post
on Wednesday that she and her "husband, friend and partner of 16 years" had decided to get a divorce.
"For some time we have been engaged in private and difficult, but thoughtful and tender undoing of ourselves," she wrote.
She added that they were determined to work together to raise Kase.
"Our dedication to our son is unwavering and we are both committed to being the best partners in raising our son," Jewel continued. "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 – we wish only what is best for our son."
