Mya and Dmitry -- who had already previously topped the judges' leaderboard for five of the competition's first nine weeks -- received a combined score of 87 out of 90 possible points for their three Monday night routines.
Mya and Dmitry received a perfect 30 out of 30 score for their initial paso doble dance and then received an additional 30 points during the performance show's "megamix" round, which required all three couples to perform a joint routine and compete for first, second and third place rankings that represented 30-point, 28-point and 26-point scores respectively.
Mya and Dmitry's perfect night finally came to an end when their freestyle round performance of a "Hairspray"-inspired routine failed to dazzle the judges.
"[It was] high energy [and] fun, but not outstanding to me," judge Carrie Ann Inaba said of the performance, which still received 27 out of 30 points from the judges.
"If you do 'Hairspray,' it was done so well the first time that you're competing with that imagery in people's minds. Adam Shankman did a great job the first time [and] you're competing with that when you do this," she added.
"I'm 100% with Carrie Ann here, there was a sameness about it, it never went anywhere," said lead judge Len Goodman. "I was expecting something to happen and it never happened."
"I was expecting something a little bit more spectacular but it wasn't bad," judge Bruno Tonioli added.
Danny and Kym earned 27 points for their initial cha-cha performance and 28 points during the "megamix" round but ended their night on a perfect note with a 30 out of 30 score for their Broadway-inspired freestyle routine.
"That was truly an absolute show-stopper," Len gushed.
"Mister Show Business at his best!" Bruno shouted. "Watch and learn! In the great tradition of Broadway, Hollywood, Vegas -- you are the master."
"We've had some really memorable freestyles [over the years]," Carrie Ann said. "Welcome to the Hall of Fame of the freestyle!"
Kelly and Louis received 26 points their initial Argentine tango and earned an additional 26 points during the "megamix" round. However they stumbled during their disco-inspired freestyle routine, which received only 24 out of 30 points from the judges after Kelly fell during the performance.
"One thing is for sure, you never looked more beautiful than tonight," Bruno told Kelly. "You had all the glitz and glamour of the disco era -- and I tell you I was there, I know what it was like -- and sometimes people fell on the floor."
"Tonight I wanted to see that you are a survivor. You were definitely a survivor, you're been that way the whole time. When you fall, you get back up. When you forget, you laugh at yourself," Carrie Ann said.
"You know I know there was a few worrying incidents but you smiled through it, you were singing -- I thoroughly enjoyed watching you," Len added.
Each of the three remaining couples will perform one more routine -- with their scores contributing to their final combined judges score total but not being voted on by home viewers who already voted based on last night's performances.
Dancing with the Stars' ninth-season mirror ball trophy winner will then be revealed based on the combination of the judges' score shares for the dancers' Monday and Tuesday night performances, and the share of home viewer votes cast immediately after Monday night's broadcast.
