Warning: Break out a box of tissues, because you won't be able to get through this touching story without becoming a blubbering mess.

Though Ellen DeGeneres' talk show revolves around her dazzlingly hilarious celebrity interviews, the program has become just as well known for bringing on non-famous individuals who are facing a time of struggle and are in need of a little boost in their lives.

This week, DeGeneres shared a video of little McKenna Stanchak singing to her mother, Dianna, who is a cancer patient in stage 4. Tiny McKenna is adorable as she croons Martina McBride's "I'm Gonna Love You Through It," a song about a husband standing by his wife's side as she faces cancer.

The video quickly caught fire on social media, and DeGeneres brought Stanchak on the show to talk about McKenna and the footage that had gained over 27 million view on EllenTube and Facebook, and to have McKenna perform the song again.

"I was diagnosed on Christmas Eve 2013," said Stanchak. "She sings to me every day. She does, and I just can't help but cry, but it's a good cry."

"I just want to take the time to thank you, Ellen, for reposting that video," Stanchak added. "It has given me such hope and courage to fight on and keep fighting this battle I'm fighting."

Stanchak was looking forward to McKenna singing McBride's song to her for a live audience, but what she didn't realize was that DeGeneres had an even bigger surprise in store: McBride was waiting in the wings to help McKenna serenade her again.

Stanchak's jaw dropped as McKenna took the stage with McBride, and as the two sang the touching song, there wasn't a dry eye in the house.
