Gwen Stefani is grateful for all she has in this life—no doubt.

In fact, the 56-year-old recently shared her experience of getting pregnant with her and ex-husband Gavin Rossdale’s third son Apollo at age 43.

“I was desperate,” the No Doubt singer recalled on Hallow March 5. “I really wanted to have another baby. I really did. And I couldn’t and I was old. And then my oldest boy, Kingston, comes up to me. He’s like, ‘Mommy, I just I really want you to have a baby.’ I said, ‘I’m sorry, your mommy’s too old to have a baby now.’”

Kingston—who was eight years old at the time—prayed on her behalf, she noted, “Like, ‘Please God, let my mom have a baby.’ And I was just sitting there going, ‘Wow, look at my little boy. He’s praying for me.’”

Gwen—who is also mom to son Zuma, 17, with Gavin—explained she hadn’t asked or taught him to do so, but that he prayed every night for her.

“I think it was like four weeks later and I was pregnant with Apollo,” she explained, “who I had at 44-years-old, naturally—totally a full-on gift.”
