Charlie Futhey, 9, Does Riff On LMFAO And Sings 'I'm Bald And I Know It' About His Chemo (VIDEO)

Charlie Futhey beat cancer when he was 5 years old for the first time. Two years later, it returned.

Now 9 years old and undergoing aggressive chemotherapy, Charlie's fight has got a new melody -- and some great dance moves. In a YouTube video, Charlie riffs on LMFAO's "I'm Sexy And I Know It" pop hit and belts out "I'm Bald And I Know It."

"People look at my head, ah! People look at my head, ah! People look at my head, ah! I -- I have cancer!" Charlie's performance begins. "When I walk in the spot, and this is what I see: everybody stops and comes toward me! I got passion in my heart, and I ain't afraid to show it, show it, show it -- I'm bald and I know it."

Charlie's treatment includes chemo, surgery and maybe radiation, according to his Caring Bridge site. The doctors found tumors on his liver, abdomen, and between his bladder and rectum. They also discovered enlarged lymphnodes on each kidney. Still, Charlie calls himself a "spitfire" on his site and refuses to let himself get down.

"He is always so positive and has kept us all upbeat," MrCharlieandMsAnnie said in the bio. "This seems to be his theme song lately."
