Have Gwen Stefani and Blake Shelton hit a road block in their relationship?

Although rumors are swirling in regard to an impending wedding, a new report suggests the couple can't decide where they should live.

“Where they are going to live has become an issue,” an insider close to Stefani told In Touch Weekly on Wednesday.

According to the report, Shelton doesn't want to be a full-time resident of Los Angeles while Stefani “feels she could never ditch California and live in Oklahoma as a full-time resident.”

“Her parents live there. The boys are in school there and all their friends are there,” explains the insider.

In addition, Stefani's three boys, Kingston, 10, Zuma, 7, and Apollo, 2, need to be close to their dad, Gavin Rossdale, who is based out of Los Angeles.

“She doesn’t want to take the boys away from their dad,” the source confirmed.

“Gwen’s told Blake she’d be OK moving out of Beverly Hills and into a nearby place like Hidden Hills, which is known as horse country because of its sprawling ranches,” the source revealed. “But Blake argues that it would still be California.”

“At heart, Blake is a very simple guy who loves to hunt and spend time on his ranch,” said the insider.

While Shelton spends tons of time on the west coast while in production on The Voice, which films the majority of its scenes in Los Angeles, his homebase is in Oklahoma and he may not be ready to change that quite yet.
