After a two-year hiatus,Peta Murgatroydis back onDancing with the Stars— and is partnered with former NBA star (and the tallest guy in the ballroom)Lamar Odom. Here, Peta details their journey thus far – the challenges, the laughs they share, and what it’s going to take to win!

Lamar went into this week being the most confident he has been since startingDWTS. He was super excited about our song and loved the fact that we were givenRisky Businessas our movie night theme. He was energized, pumped and ready to start a heavy week of rehearsals. I can see how much he wants to prove to people that he can finish a dance with no mistakes. He really does try his best and fights till the end.

Ninety-nine percent of our dance wasawesome! When Lamar jumped up on the couch, the audience went crazy. They were so loud that I got that rush of electric excitement I usually get with the partners I know I can win with. Lamar gives me that excitement and adrenaline rush. When he nails a sequence of moves, I’m so overjoyed that I want to scream it to everyone! I’m such a proud mumma and when I can feel the audience around him, it makes me want to cry happy tears.

Lamar and I have a goal for this next week with our Viennese Waltz: We will complete it withoutanymistakes! I need to make it simple enough for him, yet still effective for our audience. I want him to bring out all the emotion, as it’s a beautiful song, and show me a more vulnerable side of himself. Fingers crossed!

I’m grateful to be on this journey with him and I know that we’re here to stay!
