I’d say take this with a grain of salt because it’s from People. However, they do get a lot of exclusives on country music stories so there might be something to it.
According the magazine, Gwen Stefani and Blake Shelton can’t tie the knot because of Gwen faith. A “Gwen insider” said that the singer is Roman Catholic and wants a church ceremony.
To get remarried in the church, a previous marriage has to be annulled. And apparently that can take a really long time.
So, as of now a marriage isn’t on the table for the pair.
