With the premiere of Amazing Race All-Stars just a week-and-a-half away, some of the competing teams are set to bring their fiercest game to the competition this time around.

Team Youtube 'Done Playing Nice?'

One team, Caroline Cutbirth and Jen Wayne, country singers from season 22, are now set to be fierce competitors in their second attempt at winning the one-million dollar prize.

"This year, it is on like Donkey Kong," Cutbirth said in a pre-race interview with CBS.

Wayne explained that even though it goes against their nature, the two were set to play the game in a slightly dirtier way this time around by not being as helpful with other teams.

"Our strategy this time is we're not going to be so nice," she said. "We're going to be nice to people but we're not going to tell everybody all the information and we're not going to help everybody. It's going to be hard for us."

The two also revealed that they have been preparing themselves both physically and mentally this time around.

"We really want to race with a positive attitude and keep lifting each other up," Cutbirth said. "Of course you have human moments where it gets intense, but I think we really just want to be a positive force."

"We've been absolutely visualizing ourselves as the winners and not taking 'no' for an answer, or 'I can't' as an answer, and I think we have just been mentally challenging our mindset, that we can win this and we will win this."

The two have not only mentally prepared, but physically prepared as well, by getting into better shape.

"She has a bicep! I saw it! It looks good. It pops up and everything!" Cutbirth said.

"For the first time in my life, I have a bicep," Wayne added. "It's small but it's there."

Fans of the duo have already begun tweeting them messages of support before the race airs.

"Everyone watch out for @TXSweetCaroline & @jenwayne they are the biggest threat on @AmazingRace_CBS there competitors just don't know it yet," a fan tweeted Feb. 9.
