They're still head over heels, though.

Gwen Stefani and Blake Shelton have decided to take some pressure off their relationship, and aren't trying desperately to get pregnant anymore after over a year of trying to conceive.

"Blake and Gwen have decided to put plans to have a baby on hold. Their feeling is if it happens naturally, great. But they’ve decided to not focus on it for the time being," a source dished to Us Weekly.

"Blake is extremely attentive, loving and doting towards Gwen and the boys. Blake has always wanted children. And he’s great with Gwen’s kids, which prompted them wanting their own. He is completely at peace with the prospect of not having any biological children of his own,” the source added.

The No Doubt songstress wouldn't want to have another child out of wedlock, though.

"Gwen is very traditional and wouldn’t want to be pregnant without being married. Their relationship has grown and matured into a stable, loving union. The need to get married and have kids isn’t the priority it once was," the insider revealed.

They're one of Hollywood's most rock solid couples!
