THE MAKEOVER PROCESS OF THE HARRIS SEXTUPLETS' HOME IN BIRMINGHAM, ALABAMA IS THE SUBJECT OF "EXTREME MAKEOVER: HOME EDITION -- HOW'D THEY DO THAT?," MONDAY, MARCH 7 ON ABC

Harris Sextuplets are the First Recorded Set of Surviving African American Sextuplets

Celebrities Who Lend a Helping Hand Include Miss Piggy, Kermit, Fozzie and Animal from The Muppets, and Florence Henderson ("The Brady Bunch")

"Extreme Makeover: Home Edition: How'd They Do That? (Harris Sextuplets)" - The producers from "Extreme Makeover: Home Edition" literally open every door to show how Ty Pennington and his team of designers, workers and contractors are able to change the lives of deserving families as they rebuild the entire interior and exterior of a run-down house in just seven days. "Extreme Makeover: Home Edition: How'd They Do That?" will air MONDAY, MARCH 7 (8:00-9:00 p.m., ET), on the ABC Television Network.

On Sunday, March 6, viewers will witness how the design team came to the home of Chris and Diamond Harris, who are the parents of healthy two-and-a-half-year-old sextuplets and nine-year-old DeWayne. After DeWayne was born, the couple didn't seem to be able to get pregnant again, and so turned to a specialist for help. They were shocked when an ultrasound showed Diamond pregnant with five babies, and surprised again when they discovered at delivery time that they had a sixth baby. The Harris Sextuplets are America's first-ever surviving set of African American sextuplets.

The Harris family's house called for many things, including more space, a safer home and a much-needed playroom for six very energetic toddlers. The design team, homebuilder Signature Homes and hundreds of workers and volunteers solved the space issue to accommodate the sextuplets by building a 5,000-sq. ft. home, one of the show's largest to date.

During this edition of "How'd They Do That?," there will be a behind-the-scenes moments with some of the celebrities who lent a helping hand, including Miss Piggy, Kermit, Fozzie and Animal from The Muppets, and Florence Henderson ("The Brady Bunch"), who babysat the sextuplets when the parents went on a much-needed romantic date one night.

The design team for this episode of "Extreme Makeover: Home Edition" will feature team leader Ty Pennington, Paul DiMeo, Michael Moloney, Constance Ramos and Eduardo Xol. The series is produced by Endemol USA, a division of Endemol Holding. It's executive-produced by Tom Forman and this episode is co-executive produced by Denise Cramsey and Michael Maloy.

A TV parental guideline will be assigned closer to airdate.
