When 23-year old Dianna Stanchak was diagnosed with stage 4 Hodgkin’s lymphoma two years ago, she had no idea that her biggest cheerleader would be one of the smallest people in her life.

At a recent cancer support party for Stanchak, her four-year old daughter, McKenna, gave an emotional performance for her mom, singing along to Martina McBride's "I'm Gonna Love You Through It".

This viral video of the single-song concert was caught on camera by McKenna's grandmother who says that McKenna sings the song to her mom every day.

If this doesn't get you at least a little choked up, I don't know what will.
