It was Most Memorable Year week on last night’s Dancing with the Stars, and partners Karina Smirnoff and Corbin Bleu chose the foxtrot to express the actor’s unforgettable moment—when Bleu’s 12-year-old sister, Phoenix, was first diagnosed with scoliosis, a medical condition in which the spine is curved from side to side, in 2011. Bleu called his younger sister an “inspiration,” and dedicated the performance (set to Rascal Flatt’s “My Wish”) to her.

“We wanted to recreate a dreamy, romantic, magical dance—like a fairy tale,” Smirnoff told InStyle.com exclusively, citing the ever-popular classic Beauty and the Beast. Bleu wore a black tailcoat tuxedo with a blush pink ascot tie, and Smirnoff donned a sweetheart dress, a vibrant rhinestone belt, and a delicate bridal-inspired tiara. “Jag [Bleu’s youngest sister] and Phoenix are both obsessed with princesses,” Smirnoff told us. “Their favorite colors are pink and purple, which is why we chose those colors for our outfits.”

Bleu and Smirnoff earned 28/30 (which includes their first 10 of the season). Shockingly, Christina Milian and Mark Ballas, a high-scoring pair, were eliminated last night, leaving 8 couples in the ballroom.

Tune in next Monday night at 8/7c on ABC for the live results show.
