Bindi Irwin, Nick Carter, Alek Skarlatos and Carlos PenaVega are all headed to the season 21 "Dancing With The Stars" finale and after a long, hard journey, they have nothing but amazing things to say about their partners who helped them make it this far. Following Monday night's semifinals, the stars and the pro dancers took to Instagram to share their thoughts on not only their partners, but on what it truly feels like to have made it this far into the competition, and of course, to thank all of their fans for their support.

For someone like Derek Hough, who has made it to the finale more than any other pro dancer, and holds the record for the most Mirrorball trophies, you'd think this would be something he was used to. But when you have a partner as kindhearted and positive as Irwin come out and really surprise everyone with her incredible dancing skills, it's hard not to be grateful.

"Bindi and I have had such an incredible journey and have worked incredibly hard to get this far. So proud of Bindi for giving me her all each week and handling this intense experience with a sense of class I've never seen before," Hough captioned a black and white photo of the two.

He then posted another collage with clips of their trio dance with pro dancer Mark Ballas, who is a really good friend of Hough's. "Thanks to my bro @markballas for being a part of our trio," Hough wrote. "Always love working with you brotha. I am so proud of my @bindisueirwin. We can give you the steps, but you brought them to life! You are THE LIGHT!"

Irwin then took to Instagram to thank not only her partner for this incredible experience so far, but Ballas as well for helping her achieve yet another perfect dance. "These guys feel more like family. You ARE family. I love you both more than words!" she wrote. "Thank you for creating such a beautiful trio dance tonight. It was an absolute honor to learn and dance with you both. And to everyone, thank you so much for your support. I couldn't be here without you. I'll continue to try my best for you. We must find the light in every day. I'm determined to give this journey my all. I can't believe we made it to the finals."

Even Ballas got in on the action, praising Irwin for her amazing journey so far. "Words can't express how proud of @bindisueirwin I am," he wrote. "Your hard work, passion, focus and wonderful soul keep you shining so bright. Working with you this week was an absolute joy and I will never forget it. You were stunning tonight and I'm so happy for you...You got this and you deserve this. You bring so much love and positivity to this world and that's exactly what this world needs right now."

While American hero Skarlatos has proved he's a man of few words, his partner Lindsay Arnold took to her Instagram to express her gratitude and excitement. "OH MY GOSH!!!!! We made it to the FINALS," she captioned a photo collage of their flawless Waltz. "I cannot express how truly grateful and proud I am of @alekskarlatos he has worked soo hard and I couldn't be more happy that I have gotten to share this journey with you! Ahh love you so much Alek so proud!! Thank you all for your support and love we couldn't do it without you."

Arnold's best friend, and Skarlatos' possible love interest, Emma Slater helped them perform their trio dance, and she couldn't have been happier that they picked her to share this moment with. "I love & adore you both," Slater wrote. "Couldn't be happier you're in the finals. Alek you were wonderful tonight, so amazing. And Linds you are made to be here, no one could have done a better job. You're so talented and beautiful and my best friend (so yay!!!) You know I'm voting for you both."

Carlos had a rough week last week when he had to say goodbye to his wife Alexa after her elimination, but he came out last night and really gave it his all for not only her, but his partner Witney Carson, who could not be more proud of his journey. "Tonight was magical! Even though this week was tough we pulled through & made each moment count!" she captioned a photo from their dance. "You have made me so proud @therealcarlospena. Thank you for being my teammate in this, pushing me to become a better artist and taking risks! Now, let's finish this thing right!"

He's just as determined to win, but he knows that everything happens for a reason and is just happy to have made it this far. "Regardless of what happens #Godisgreat and I am so thankful for this entire opportunity!!!! I want to win this for all of you!!!" he captioned a selfie of him and Carson.

He then posted another shot from their dance asking his fans to vote and thanking his partner in the process "@Witneycarson YOU were amazing tonight!!" he wrote. "I could not ask for a better partner!! Thank you for being so supportive!! Dancing with you HAS BEEN INCREDIBLE!! Don't let anyone tell you your less than amazing!! We can win this thing!!"

After a somewhat rough night, Carter put their low scores aside and really took the moment to thank Sharna Burgess and his fans for being the reason he's made it this far into the competition. "I don't think you'll ever realize how grateful I am. I know you've been rooting for me and voting, and trust me, I see it," he captioned a photo of the two. "Thank you will never be enough I love each and every one of you."

Burgess also posted a photo of the two thanking all of their fans for their votes. "Thank you #teamsharnick lovers, you got us to the final!! We are so excited and grateful to get to dance one more time for all of you. @nickcarter as always you made me so proud tonight. I've loved every minute of this journey with you!" she captioned the selfie and then posted another photo of their dance writing, "My @nickcarter you shared so much of yourself with all of us this week. This journey hasn't been easy for you, along the way we have over come so many obstacles and faced fears together. We had a real moment tonight and together we came back and finished strong. We are a great team and beyond that great friends. I adore you and I'm so grateful for everything you are."
