To show their support for Idol finalist Blake Lewis, the Seattle-based singer's cheering squad has been sporting shirts emblazoned with "Blaker Girl" or "Blaker Boy" across the chest when they attend the show.

"After Blake's first audition, he was hanging out with me and a couple of our friends and we were joking around, coming up with a silly slogan," says Blake's childhood pal Kristi Redman, who noted that the name was inspired by former Laker Girl Paula Abdul. But Redman & co. soon got serious about making pro-Blake paraphernalia as the singer kept advancing in the competition.

Now shirts ranging from $15 to $20 along with baby onesies, buttons and hats are available on blakergirls.com with 50 percent of the proceeds going to the Children's Hospital and Regional Medical Center in Seattle, in honor of Blake's friend Brad Boyle and Brad's girlfriend Heather Krich, who were both diagnosed with lymphoma within two months of each other.

"Blake was always going to visit them in the hospital and making sure they were okay, being a friend basically," says Redman, who says they have raised about $1,000 so far. "It was really important to him now that he has this platform to do something positive in addition to all that he's doing on American Idol."
