Pump the brakes. Gwen Stefani and Blake Shelton are putting their baby plans on hold — permanently. Gwen decided to call off her dreams of having a child with the country crooner and focus on their wedding and future together.

However, that decision did not come easy for the 47-year-old rocker. Sources reveal exclusively to Life & Style that Gwen is scared Blake, 41, will regret his decision not to have his own kids. “Blake always told her that he didn’t need to have a baby,” the insider says. “Gwen still has fears that one day Blake could end up regretting it. But for now, they are happy.”

The pair, who have been dating for over a year since meeting on The Voice, was consumed with having a baby — but they decided raising Gwen’s three boys, Kingston, 11, Zuma, 9, and Apollo, 3, with ex Gavin Rossdale, would be more than enough. “It put too much stress on Gwen and Blake and took a real toll on their relationship,” the source adds.

As Life & Style previously reported, the “Hollaback Girl” singer was trying to get pregnant naturally after IVF treatments were unsuccessful. “She’s determined to have another baby and carry it herself, even though Blake has said it doesn’t matter if they adopt or get a surrogate,” a source said. “Physically and emotionally, it was just a lot for her. So she’s trying to get pregnant naturally for the time being.”

As for Blake, he is taking his stepfather role seriously, and recently featured Gwen’s sons in his latest music video for “I’ll Name the Dogs.” “Gwen cried the first time she saw the finished video. The combination of the romantic lyrics that Blake sings just for her, seeing her boys on screen, and the surprise twist of it being an older couple getting married hit her right in the heart,” a source told Hollywood Life. “It was so emotional for her in so many ways.”
