LC to Teen Choice: I'm Not Worthy!

TMZ has learned LC is giving up the surfboard she won at this year's Teen Choice Awards for living her life on TV to someone a lot more deserving -- a 13-year-old Leukemia patient who was up for the $100,000 Do Something Award and lost.

Conrad met the kid, Pat Pedraja, at a Teen Choice pre-party Saturday where she presented him with $10,000 check from Do Something for his work recruiting bone marrow donors from minorities across the country.

We hear she personally slipped him an iPod Touch she filled with her favorite music. It ain't $100,000 bucks -- but we're working with a reality TV budget here.
