They've got their eyes on the prize.

Gwen Stefani and Blake Shelton are actively trying to have a baby, and it has taken precedence over tying the knot, although that's in the plans was well, Us Weekly reports.

"[Gwen and Blake] will get married one day, but right now they are hyper-focused on getting pregnant. They believe there is still a chance for Gwen. They are incredibly hopeful," a source dished to the mag.

The 48-year-old No Doubt singer got pregnant with son Apollo when she was 43, and they think that's a good sign she's still capable of popping out another kid. The country crooner was open about his desire to have a biological child right at the beginning of their romance.

"Blake told Gwen he does want kids of his own, and Gwen was willing to try. With her, Blake has the exact relationship and family life he’d hoped to have with Miranda. Gwen’s everything he wants. Gwen and Blake started talking quickly about having a baby," the source added.

After trying for at least a year, they're realizing it might not be as easy as they once hoped.

"Starting a family has not been easy for them. It’s something that they really want and it’s just not working out the way they wanted it to. They struggle they’re facing is making them stronger. They are so committed to one another and protective of one another," the insider revealed.

We're not so sure she doesn't already have a bun in the oven!

The past two times we've spotted her, we've speculated that she's pregnant because of her fuller looking tummy and the fact she goes out of her way to hide it! Just this Monday, she pulled the whole "purse covering the stomach" trick, so we're officially on bump watch!
