He and Gwen Stefani announced their split three months ago, but Gavin Rossdale is still wearing his wedding band – why?

“He wears it for the kids because it makes them feel good,” an insider tells PEOPLE of Rossdale, who was spotted out and about wearing his ring on Friday.

Since going public about their divorce in August, Rossdale, 50, and Stefani, 46, have been putting their sons – Kingston, 9, Zuma, 7, and Apollo, 20 months – first.

“There is an ongoing conversation with the boys to make sure they are as happy and comfortable as possible,” a source told PEOPLE last month. “To both Gwen and Gavin, the boys are their number one priority and concern.”

And the rockers exes are both moving forward with their lives. Rossdale is working is working on music, including a new Bush album. Meanwhile, Stefani is busy on The Voice coaching panel and, as PEOPLE confirmed exclusively last week, is dating her costar Blake Shelton.
