Gavin Rossdale Gushes Over Wife Gwen Stefani: "She’s a Great Girl, I'm Lucky!"

Actor also says more kids could be a possibility

It's no easy task for Hollywood couples to stay happily married for more than 10 years.

But for Gavin Rossdale and his wife, Gwen Stefani, everyday is special.

"To be with one person for a very long time actually gets more interesting," the actor told E! News at The Bling Ring premiere. "I'm into that. She's a great girl. I'm lucky."

With their relationship stronger than ever, could the happy couple be expanding their family with more kids?

"I don't know," Rossdale said with a smile. "Maybe tonight, who knows?"

In the meantime, the proud dad is looking forward to spending Father's Day with his wife and two kids, Kingston and Zuma.

"She's always got a surprise," he said. "I'll just let it roll. I let it reign on me in a beautiful way."
