Robert Irwin on Instagram: "BEST NIGHT EVER! Our first dance! I started my rehearsals without the slightest idea of how to dance and I am just so grateful to @witneycarson for being the most incredible teacher. This show means the world to me and I am pinching myself that I get to live out a childhood dream. And how special to have my family here to celebrate with me. Team IrWINit are here to bring passion and positivity into the ballroom! Week one done, onto the next! 睊"
