While the pair was dancing to "Somewhere Over the Rainbow" -- Alley's pick for her personal story routine -- Chmerkovskiy fell while holding the actress, 60, sending them both to the floor.
"My thigh just gave out. I'm so sorry. I'm so sorry," Chmerkovskiy said later. "It has nothing to do with her."
The couple were taking on an emotional dance, telling the story of Alley's move to Los Angeles and the sudden death of her mother, when they fell. They managed to get back up and finish their routine, but they both seemed to be in pain.
The judges seemed to be moved by the performance despite the fall, giving the pair 21 out of 30 points.
"Sometimes tragedy leads to an amazingly beautiful moment," Carrie Ann Inaba said, noting that after their tumble "something magical happened."
"You've overcome it," said Len Goodman. "You got up and dusted yourself off."
And Bruno Tonioli added, "You can't keep good talent down. Once you got up it was better than ever."
It seems Alley took her positive reviews to heart and isn't going to let their fall keep her down. "There's something exciting about live TV," Alley said after the show. "I'm so scared because something can happen and now that it's happened I'm like, 'so what?'
And later, she made it clear that she has no hard feelings towards Maks. "I salute u... U r a gladiator," she twittered at her partner. "A champion... I'm honored to be your partner."
On Tuesday, she added, "Maks is too humble.. we all know it takes TWO to Tango..on our feet or on our asses...it takes TWO ..I will do better from now on...xoxo"
Though Maks seemed to be in serious pain following their performances, both he and Alley insist that he's doing fine and will continue dancing as planned.
