Mark Ballas follows Aly Raisman outside a dance studio over Easter weekend in Los Angeles on Sunday afternoon.

The twosome put in one last practice for their Viennese Waltz for tonight’s Dancing With The Stars.

“It’s a really cool surprise. I can’t really say more than that,” Aly told TVGuide about their dance. “It’s not a clichéd, cheesy thing at all. I like it a lot. I hope people understand it and like it. It’s mature, so hopefully I’ll be able to pull it off.”

Aly continued of her improvements on the dance floor, “The Viennese waltz is eight-count, whereas the others were four-four counts, so that’s new. But I’m definitely improving each week. I’m getting more and more comfortable with the music and really understanding it, whereas before I just listened to the song. Now I listen to the instruments and the beat and the lyrics.”
