Must-See Video: Kelly Clarkson’s special message to the Seattle Children’s Cancer patients - The singer has been touched, much like so many people around the world, by Chris Rumble's inspirational message of hope in his version of her Kelly's hit song "Stronger"

Yesterday we wrote about the inspiring Chris Rumble, who 35 days ago was told by doctors that 95-percent of his blood was full of leukemia cells.

The 22-year-old has been staying at Seattle Children’s Hospital, and last Saturday he enlisted in the help of fellow patients, doctors and nurses and created his own version of Kelly Clarkson’s hit song, “Stronger.”

Since posting it on Sunday morning, the clip has now amassed a staggering 640,000 hits and it’s growing by the day.

In response to the video, Kelly Clarkson has now posted her own clip on YouTube, in which she sends her personal gratitude to the patients.
