Fergie, 44, filed in Pasadena, California, on Friday. The couple, who had dated since 2005, were wed in 2009. They have one son together, Axl, 5.
In 2017, Fergie and Josh, 46, confirmed they were no longer together, sharing in a statement: "With absolute love and respect, we decided to separate as a couple earlier this year. To give our family the best opportunity to adjust, we wanted to keep this a private matter before sharing it with the public. We are and will always be united in our support of each other and our family."
In October 2017, Fergie said on "The Wendy Williams Show" that she never wanted to get a divorce, and that she "wanted to stay married forever."
