Gwen Stefani and Gavin Rossdale had a nightmarish day last week when their 2 1/2-year-old son, Zuma (pictured right), fell from a countertop on Thursday and broke his arm.

"It was probably one of the worst nights of our life," Rossdale told Us Weekly while at a party in Las Vegas. "It was a freak accident. He fell."

After rushing their son to the hospital, Rossdale says that Zuma is recovering well. "He's doing good now. Kids, they find a way," the Bush frontman added. "You feel so much when something happens to [your] kids. It's the worst thing in the world."

Rossdale married Stefani in 2002 and the couple had their first child, son Kingston, in 2006. Two years later, the pop star and fashion designer gave birth to their second son, Zuma. Rossdale also has a 22-year-old daughter, Daisy Lowe, with singer-songwriter Pearl Lowe.
