Is Gwen Stefani’s Catholic Faith Keeping Her from Marrying Blake Shelton?

A source tells “ET” that even though they’re in it for the long haul, they’re in no hurry to exchange rings.  One reason is because things are going so well they haven’t felt the need to change anything.

And then there’s Gwen’s Roman Catholic faith.  Even though she and Gavin Rossdale are divorced, the Church doesn’t allow remarriage until the previous one has been annulled.  That hasn’t happened yet.

The source says,, “Religion is very important to Gwen and Blake has been so respectful of that.  She doesn’t take her Roman Catholic faith lightly but of course, has to apply it to her life today.

“She’s head over heels in love with Blake and they both want to spend the rest of their lives together.”  The source adds, “Their friends are sure a marriage will happen soon enough.”
