We still can't believe Gwen Stefani and Gavin Rossdale are dunzo -- but it sounds like she's already moving on!

On Sunday the No Doubt singer went to church with her family, which has been a pretty regular thing for her these days. Earlier this month she went to services with her three sons, along with her parents Dennis and Patti. Both times we've spotted her she has definitely NOT been wearing her wedding ring.

Earlier this month Gwen and Gavin Rossdale announced their split, and shortly after that it was reported that Gwen filed for divorce because she suspected Gavin cheated. Yikes! On top of that, it was also reported that Gavin was totally blindsided by Gwen's filing. A source told Radar, “They’ve had problems as a couple before but have managed to work through them without going into therapy or attempting a separation. This time Gwen went through with it because she wanted a change, and Gavin is pretty devastated.”

To be honest, we were pretty shocked about this one as well -- think Gwen and Gavin will ever get back together?
