Jana Kramer's water-soaked Argentine tango with Dancing With the Starspro partner Gleb Savchenko was a real crowd-pleaser, but it almost didn't happen!

"When he told me what we were going to do, he was like, 'OK, you're starting in a bed ... and you're ending in a shower,'" Kramer told ET inside a recent dance rehearsal. "I was like, 'Wait. What?' I was freaking out."

The two only practiced the dance twice with water, and it was fraught with problems. Neither of them could keep their footing, and Kramer was practically choking on the water falling from the ceiling. Still, the dancing duo managed to pull it together for one of the sexiest performances in DWTS history.

"I saw the standing ovation from all four judges," Kramer recalled. "That was the coolest feeling."

"That was my first perfect score ever," Savchenko said.

Now, Kramer and Savchenko are aiming to ride the momentum from their last performance all the way to the mirror ball trophy.

"My goal going into this was to get a perfect score, so now I'm like, 'Hmm... the mirror ball," Kramer said. "Give me more. I've got the taste of it."

While Kramer grinds away in the dance studio, she has also been busy outside the ballroom with a new single, "Circles," which is dedicated to her 8-month-old daughter, Jolie.

An all-new Dancing With the Stars airs Monday at 8 p.m. ET/PT on ABC.
