Baby #4 for Hanson Brother

Talk about a blast from the past.

The middle brother from pop group Hanson is all grown up at the age of 24, and People.com reports that he just welcomed a new son with wife Natalie on Tuesday.

According to the report, the proud parents named their new arrival Viggo Moriah, and he came weighing in at a healthy 8 lbs., 5 oz.

Things are going well as the couple told the magazine, "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."

Wait there's more than one?

Yup. Actually, newborn Viggo makes child number 4 for the young couple as they have sons Ezra, 6, and River, 2, along with daughter Penelope, 3.

Taylor isn't the only family man of the Hanson trio though. Between brothers Zac and Isaac, Taylor's children have three cousins: Everett, 1, Shepherd, 6 months, and Monroe, 5 months.

Besides taking the time to reproduce, the Hanson brothers have recently released a book, Take the Walk, that chronicles their humanitarian efforts to help fight AIDS and poverty in Africa.

The once teen sensation hasn't given up on their music either, and reportedly have plans to head to the studio early next year with a new album expected by the summer.
