Singer Taylor Hanson's brood has just got bigger - the rocker and his wife Natalie have welcome their fourth child. The Hanson frontman, 25, and his wife - who he married in 2002 - welcomed son Viggo Moriah on Tuesday in his hometown of Tulsa, Oklahoma.

And the couple insist their new arrival is the best present their growing family could ask for this holiday season.

The couple tell People.com, "Viggo is doing great. He is the perfect early Christmas gift. We look forward to being home to enjoy the holidays with him and his very excited brothers and sister."

Hanson, the middle brother of the "MMMBop" trio, is dad to sons Ezra, six, and River, two, as well as daughter Penelope, three.
