The 42-year-old singer has two sons, Kingston, six, and Zuma, four, and she is happy with her family and sees no reason to add to her brood, reported Contactmusic.
"Do I want more children? Not really, no. Two kids are enough. I'm done with having children. I'm tearing myself up every day as it is," she said.
Stefani has been married to Rossdale for 10 years, and she said that at times their relationship have its difficulties, but they are both very happy with each other.
"We have found a way to handle it. Of course things are sometimes running better and sometimes not so great. But we're always very happy that we've been together this long.
"We stick together and on the main things we agree. We both wanted a family, for example. Gavin is a fantastic father. I could never record a song with him, but the guys are our great common passion," she added.
