Little girl has big surprise for mum when she appears on Ellen

Last week we shared a video of adorable four-year-old McKenna singing to her mum battling cancer.

After being posted on The Ellen Show's Facebook page, the video has been viewed over 27 million times.

So Ellen invited McKenna, her mother Diana and grandma Dee onto the show. McKenna treated to her mum to another rendition of 'I'm Gonna Love You Through It' in a surprise duet with the song's original singer Martina McBride.

It was, understandably, an emotional performance (especially when McKenna sings 'I'm gonna wuv you through it') with Ellen presenting Diana - who is battling stage four cancer - a cheque for $20,000 to help with medical expenses.

You can watch the full video here. Excuse us, we have have something in our eye.
