"EXTREME MAKEOVER: HOME EDITION" CATCHES "BIEBER FEVER" WHEN POP SINGING SENSATION JUSTIN BIEBER SURPRISES THE BROWN FAMILY FROM WELLMAN, TEXAS, WHO LOST THEIR TEENAGED DAUGHTER IN A TEXTING-WHILE-DRIVING ACCIDENT

Additional Celebrity Participants Include Actress Emma Roberts ("Nancy Drew," "Valentine's Day") and NASCAR Superstars Carl Edwards and Greg Biffle

"Brown Family" - The Brown family from Wellman, Texas is still recovering from the loss of their talented teen-aged daughter, Alex, to a texting-while-driving accident. Parents Jeanne and Johnny Mac, along with their 12-year-old daughter, Katrina, have made it their life mission to prevent others from having the same fate. To help spread their life-saving message across the country, celebrity volunteers, including pop singing sensation Justin Bieber, actress Emma Roberts and NASCAR superstars Carl Edwards and Greg Biffle, all signed a pledge promising that they will not text while driving. This two-hour episode of "Extreme Makeover: Home Edition" airs SUNDAY, JANUARY 30 (8:00-10:00 p.m., ET) on the ABC Television Network.

Seventeen-year-old Alex Brown epitomized the All-American girl -- beautiful, smart, vivacious and beloved by everyone who knew her. Tragically her life and her dream of a career in broadcast journalism were cut short in November 2009. Dedicated to making sure no other family suffers such heartbreaking loss, the Browns decided to turn their tragedy into something constructive, and travel to local high schools with Alex's wrecked truck on their flat-bed trailer to remind young people of the dangers of distracted driving. Their goal is simple: They want to save lives.

While the EM: HE design team and volunteers replaced this deserving family's rundown double wide trailer with a new home, the Browns went on vacation to New York City. On a side trip to New Jersey, designer Paige Hemmis surprised Katrina by bringing in five of her hometown girlfriends. But the biggest surprise was yet to come when Paige introduced them to teen superstar Justin Bieber.

The lucky young ladies got to talk to The Beeb about his upcoming movie, "Never Say Never." The conversation turned serious when Justin told Katrina that he too supports the message about educating youth and adults of the dangers associated with texting and driving. Another bombshell was in store for Katrina when she learned that her parents and friends were invited to Justin's sound check and would be his special guests at that night's concert.

The design team for this episode is team leader Ty Pennington and designers Paige Hemmis, Michael Moloney, Leigh Anne Tuohy, as well as local builder Palm Harbor Homes and community volunteers. "Extreme Makeover: Home Edition" is produced by Endemol USA, of Endemol Holding, and executive-produced by Brady Connell & George Verschoor. David Goldberg is Chairman, Endemol North America.
