Some find it hard to know just what to say or do when a love one is diagnosed with cancer. But 4-year-old McKenna found the perfect way to express her feelings, fears and love to her mother.
McKenna's mother, Dianna, is battling stage-4 Hodgkin's lymphoma, and in a video that recently went viral, the tot can be seen serenading mom with Martina McBride's touching hit "I'm Gonna Love You Through It."
But now they're both the stars of a new video — and they're joined by yet another star.
On Tuesday, Ellen DeGeneres invited the family to her show and had a special treat for Dianna.
"McKenna is going to sing to you right now," she said. "We wanted her to sing with someone, so ... Martina, come on out!"
Yes, McBride hit the stage for a duet with the little girl, and their sweet song had mom in tears.
But don't worry, Dianna said that McKenna's singing always brings tears to her eye for "a good cry."
In fact, even though McKenna doesn't usually have an award-winning Nashville artist at her side, she sings that song every single day to her mom.
Given the lyrics, it's easy to see why: "When you feel lost and scared to death, like you can't take on more step, just take my hand, together we can do it — I'm gonna love you through it."
We wish the best for Dianna and her whole family!
