Bush singer Gavin Rossdale and No Doubt star Gwen Stefani decided to divorce in August, but the English rocker is still wearing his wedding ring. Even though it would seem that the reason is that he still has feelings for his ex-wife, who he was married to for 13 years, it’s because it makes their children happy, People magazine wrote in an exclusive report Monday.

Rossdale, 50, was pictured Friday with the band on that finger. "He wears it for the kids because it makes them feel good," an insider told People. He and Stefani, 46, share three children together: Kingston, 9, Zuma, 7, and Apollo, 20 months.

Both celebrity parents are looking out for their children. "To both Gwen and Gavin, the boys are their number one priority and concern,” a source told People last month. "There is an ongoing conversation with the boys to make sure they are as happy and comfortable as possible.”

While Rossdale is still wearing his wedding ring, “Used to Love You” singer Stefani has moved on. She started a high-profile relationship with Blake Shelton, her co-star on NBC's “The Voice.” The two denied their relationship for weeks, but came forward on the same day as the CMA Awards in Nashville, Tennessee, last Wednesday. "Gwen and Blake are longtime friends who have very recently started dating,” her rep told Us Weekly.

Even though most people already know, she’s afraid to reveal her relationship on “The Voice.” “It makes her slightly anxious,” an insider told Hollywood Life Monday. “She doesn’t want to make a spectacle of their relationship and she definitely doesn’t want her kids to see her acting out of character on TV with a man that isn’t their dad.”
