There are a lot of perks that come with being a rapper, but even with all the success and recognition, Mac Miller still finds time to give back. Not only did he donate $50,000 to the Make-A-Wish Foundation, but Miller joined a cancer-stricken fan in the studio to lay down a track. 18-year-old Pittsburgh native Bobby Stewart has T-cell lymphoma, and he's also a rapper and passionate hip-hop fan. Watch the news clip above to see Bobby and Mac in the studio.
"Feeling like your music really does something for the world makes it all worth it, no matter what," Mac explains. "From now on, no matter what happens for the rest of my life, no one can take that away from me."
