In a lengthy caption on an Instagram photo collage of the dancing duo, the 26-year-old wrote, "As my journey as your partner comes to an end and your next season with a whole new partner and new experience begins, there are a few things I thought about today. I honestly don't know if I have words to describe what this past season or this tour, but most importantly our partnership has meant to me. I know I have tried on many occasion while on tour to describe to the audience what I felt but I have always fallen short to put in words how I feel. So I'll do my best."
"First I have to thank you as my teacher for challenging me everyday through your own passion and dedication to your art, for pushing me past the limits of what I believed I was capable of and even for occasionally driving me crazy with trying to make all of our dances the best they could be," she added.
But that's only one thank you from the daughter of Bruce Willis and Demi Moore.
"Secondly I thank you for believing in me when I didn't believe in myself for putting up with me when I was scared or insecure, and being the person that didn't let me feel like I could fail no matter what anyone else said," she shared.
And the gratitude doesn't stop there.
"I am truly grateful to call you my friend and I am so proud that we won together, I wouldn't have wanted to do it with anyone else. I can't wait to root for you next season. Love to you always," she ended her caption sweetly.
But wait, there's more love to share!
Chmerkovskiy himself also shared an Instagram photo of the duo with his own endearing words, writing, "It isn't the end, just the beginning. Next season will begin however, and I will embark on yet another journey.. with a new partner.. but you my friend have been an absolute pleasure. Seeing you grow and become a proud young woman with your head held high and your star shining brighter than ever has been one of the most rewarding things I have ever done. We'll dance again, I promise."
The dance pro also expressed his support and gratitude for Willis, adding, "But know regardless of what we do from here on and where we go, you'll always have me cheering and rooting you on.. and kicking your butt of course.. from the side. I'm so proud of you...thank you for letting me be part of your story. Love you champ."
Willis spoke to ET last month about how excited she is to take on the part.
"Obviously so many different women come into this role," she said. "I feel like they do a really incredible job of making sure that each woman that comes in is really able to make the character her own. I sat down and Just to being able to put on the wig and have the whole character come together has been incredible."
