The finale of the Star Plus show will be aired March 23.
"There is a lot of excitement and first of all, a lot of gratitude as we have reached here only because of the love and support of our audience," Ravi said here Saturday at the CID Veerta Awards.
"So, we are so full of gratitude and it's just a matter of a week, and we have the finale. We are looking forward to it," he added.
Stand-up comedian Bharti Singh, who was also a participant on the dance reality show "Jhalak Dikhhla Jaa", is also rooting for Ravi and Sargun.
"You all will see, they are the winners of 'Nach Baliye'! They will surely win because all my votes are with them. I know they have worked very hard," Bharti said.
The other three finalist couples on the show are Neelu Vaghela-Arvind Kumar, Mahii Vij-Jai Bhanushali, and Suhasi-Jaisheel Dhami.
The show kicked off Dec 29, 2012 with 11 couples.
