Wow. I am completely impressed! Please check out the video below from our friends at Causecast.org, which focuses on the Hanson brothers "Talk The Walk" where the brothers gather together a bunch of fans before their shows in various cities to take a "barefoot" walk to raise money and awareness to hlep end poverty in Africa!

Taylor Hanson & Wife Welcome Their 4th!

The Hanson brothers, or as we like to call them, the original Jonas Brothers, have welcomed another baby into their large clan! Middle brother, Taylor Hanson, 25, and his wife welcomed their 4th baby, Viggo Moriah, this week in Tulsa, Oklahoma.

"Viggo is doing great. He is the perfect early Christmas gift," the couple says of their 8 lb., 5 oz. arrival. "We look forward to being home to enjoy the holidays with him and his very excited brothers and sister."

Viggo joins older brothers Ezra, 6, and River, 2, and sister Penelope, 3. The growing Hanson family also includes their cousins, Isaac and Zac's kids, Everett, 1, Shepherd, 6 months, and Monroe, 5 months.

Geez, tons of Hanson spawn everywhere! Hanson plans to get back into the studio early next year and hope to release a new album by the summer. Looks like they're taking a break from well, reproducing, to record a new album!

The Most Fertile Pop Brothers in America

These guys just don't quit! Taylor Hanson is continuing the family tradition of reproducing more Mmmbop spawn left and right! The middle Hanson brother announced he's expecting his fourth child with wife, Natalie.

They told PEOPLE that they "can't wait for this guy to join the party." A crowd is more like it! Well, congratulations to the couple, we all love celeb babies! Although, they are pretty low-key babies on the Hanson homefront. This will be the sixth child among the Hanson trio, as Isaac has two kids and the youngest Zac just recently welcomed one.

More Hanson Baby News...

The Hanson brothers, famous for their late 90s pop success and the song, "Mmmbop," have been busy making tons of babies with their wives lately! It's becoming a clan, seriously. Middle brother, Taylor Hanson, 25, already has three children and youngest brother, Zac Hanson, 22, has one child.

Eldest brother, Isaac Hanson, 27, and his wife welcomed their second child on July 1st! The 'MMMBop' singer and his spouse - who have a one-year-old son Clark Everett - welcomed their second child, James Monroe Hanson, who weighed 8lb 11oz, in their hometown of Tulsa last week.

Isaac, who refers to both his sons by their middle names, said: "The addition of Monroe to our family is incredible and exciting. With Monroe and Everett being so close in age, it will be great to watch them grow up together. Two little boys is going to be twice the fun!"

Isaac Hanson, 26, hospitalized in Dallas

The eldest member of the pop-turned-rock group, Hanson, was hospitalized on Wednesday night after complaining about chest and shoulder pain! Poor guy. Isaac Hanson, 26, was taken to Baylor University Medical Center on Tuesday night after a show at the House of Blues in Dallas. He is listed in stable condition. A Dallas-Fort Worth television station reported that Isaac was diagnosed with a pulmonary embolism, which occurs when a blood clot in the extremities breaks away and travels to the lungs. Ouch! Isaac's condition has forced the band to cancel their show which was scheduled for tonight in Tulsa, OK. Hanson is best known for their 1997 single, "Mmmbop."
