This Sunday's edition of Extreme Makeover: Home Edition will feature a special two-hour focus on a Texas family named Browns. Along with a 16-year old singer named Justin Bieber.
The singer makes an appearance because one of the causes closest to his heart is the prevention of individuals texting while driving - and, tragically, the Browns' oldest daughter, Alex, died in just such an incident.
In the following clip, Justin tells the family that one dollar from every concert ticket sold that night was donated to charity. He then invites 12-year-old Katrina Brown and her friends to a sound check party.
