Singer Gwen Stefani has two sons with her husband Gavin Rossdale – Kingston (born 2006) and Zuma (born 2008).

She tells Glamour magazine:

“I’ve always worked really hard and the hardest thing I’ve ever done is have kids! All of it (is difficult). Everything from getting up in the morning to trying to be consistent to trying to have the right feelings. But, of course, the rewards are so great.”
