It was fusion night on "Dancing With the Stars: All Stars” tonight – in more than one way.

Not only did couples fuse two dances together, Shawn Johnson and her new partner, Mark Ballas, tested whether they still had the glitter-ball-winning connection of 2009. Ballas stepped in for the injured Derek Hough.

Johnson had trained with both partners, hoping Hough would be healthy for tonight’s dance card, a physically challenging performance that required the fusion of two distinct dances chosen by other contestants  – in Johnson’s case, the Tango/Paso Doble.

But she faced a difficulty other contestants didn’t – uncertainty about who her partner would be until today.

With “two dances, two partners,” dealing with her own knee injury and not knowing who she would be dancing with, Johnson said the week was chaos and pretty crazy.

Does the 2009 magic with Ballas still exist in season 15?

Viewers won’t know until next week. There is no elimination this week because of Tuesday’s election, and this week’s results will be averaged with next week’s.

But the standing ovation and comments from host Tom Bergeron are encouraging.

“You two haven’t lost a step, I’ll tell you,” he raved.

Judges agreed, giving Johnson a perfect score – her first this season – and enough superlatives to fill a thesaurus.

Judge Bruno Tonioli proclaimed Johnson “the queen of the night” and said the two dances were “performed to the maximum purity of each dance, so intertwined you couldn’t tell them apart.”

Judge Carrie Ann Inaba raved that “if there’s a picture of video of what dance fusion is supposed to be in the dictionary,” Johnson and Ballas posed for it.

“Fantas-tico!” she cheered.

“You are the firecracker,” Judge Len Goodman said. “The tango fizz and the paso the explosion.”

Johnson picked up another eight points in the swing dance marathon featuring all seven dancers employed their floor craft in the classic ballroom competition. The first person eliminated received four points, the last 10.

With Monday's perfect score, Johnson, who had to retire from gymnastics competition this summer because of a knee injury, moves closer to another glitter ball trophy in the 15th season of the ABC network’s show. The 20-year-old gymnast claimed the Season 8 title in 2009.

Two celebs will be eliminated next week when the show, which airs locally, returns to its regular time slot at 7 p.m. on Mondays and Tuesdays.

Still alive are Johnson, Emmit Smith, Gilles Marini, Kelly Monaco, Kirstie Alley, Melissa Rycroft and Apolo Anton Ohno.
