After sharing their stories, the Eller and Allgood families join Oprah onstage. Then, she fills them in on the secret she and her team have been keeping for weeks. "I want to just say that angels come in all forms, and everybody has one," she says. "Yours today is an angel who is a Grammy-winning superstar and the creative genius from the Black Eyed Peas...and actually one of my favorite people, will.i.am."

What these families don't know is, for the past few weeks, will.i.am and Oprah's team has been digging through their finances. They discovered that John and Cheryl owe more than $250,000 on their home, and Alycia owes about $100,000 on her home.

Since foreclosure is imminent, will.i.am is stepping in to help. "will.i.am is paying off both of your mortgages!" Oprah says. "You will own your homes free and clear."
