"EXTREME MAKEOVER: HOME EDITION" LENDS A HELPING HAND TO A SINGLE MOTHER WHO LOST THE LOVE OF HER LIFE IN A SUDDEN AND TRAGIC ACCIDENT, BUT FOUND INSPIRATION IN THE ORGANIZATION THAT HELPED HER THROUGH IT ALL

Usher and Selena Gomez Volunteer for "Get on the Bus" Campaign

"Scott family" -- On October 17, 2009, "Extreme Makeover: Home Edition" traveled to Clarksville, Tennessee � celebrity volunteers Usher and Selena Gomez guest in the episode -- to give Trina Scott and her three daughters the good news that their problem-ridden home would be rebuilt in just seven days. This episode of "Extreme Makeover: Home Edition" will air SUNDAY, DECEMBER 6 (8:00-9:00 p.m., ET) on ABC.

Trina, 44, met her husband Dave while he was serving with U.S. Army Special Forces in Fort Bragg � and it was love at first sight. After his discharge, Dave became a Clarksville police officer. In 2002, he and his partner were on duty when their police car was violently struck by a truck. The car spun out of control, hit a guardrail, caught fire and killed both Dave and his partner almost instantly. Overwhelmed with grief, Trina turned to a group called Concerns of Police Survivors, Inc. (C.O.P.S.), which helps the surviving family members of officers killed in the line of duty. Inspired by the help she received from C.O.P.S., Trina devoted all of her free time to the organization and became its President in 2003. The time that Trina dedicates to C.O.P.S. represents essentially a full-time job, and that's on top of the full time job she works to support her three daughters -- Leyla, 17, Deidie, 13, and Alethea, 11. Trina has spent more than $20,000 on the mounting repairs to her small home, but the structural problems caused by termites and water damage remain.

The Scott Family went on vacation to Disneyland while "Extreme Makeover: Home Edition" team leader Ty Pennington, designers Michael Moloney, Paige Hemmis and John Littlefield, spearheaded the design efforts for their new home. Also of note for this episode, Usher lends a hand to Paige and John, working side by side to help make the new Scott family house a home; and the family gets to visit Selena Gomez on the set of "Wizards of Waverly Place."
