Despite having the daunting task of preparing for last week's American Idol seventh-season finale, eventual winner David Cook still took the time to visit a friend in need of support.

Cook traveled to a Los Angeles hospital to see former Idol seventh-season semifinalist Luke Menard, who was recently diagnosed with Stage 2 Hodgkin lymphoma.

"I love Luke and I just wanted to show up and make sure that he understood that I love him and know that if there's anything I can do for him and his wife, sign me up," Cook told People in a Wednesday report.

Menard was eliminated in early March on the cusp of becoming one of the Top 12 finalists -- but before he was booted, the 29-year-old from Crawfordsville, IN said he became good friends with Cook and fellow seventh-season contestants Michael Johns and Jason Yeager.

"Luke, Michael Johns, Jason Yeager and myself, we kind of buddied up one day at Hollywood week," Cook told People.  "We called ourselves the four horsemen. Any time one of your own is going through something as horrible as that, it makes everything else seem a little bit insignificant."

Cook is familiar with supporting a loved one with cancer -- as his older brother Adam has been battling brain cancer for 10 years.  

"Cancer is a very big part of my existence," Cook told People.  "I'm excited to be put in [the spotlight] where I can hopefully do something to help other people."
