Zinta, 40, who is one of the judges on the show's seventh season, is "surprised" to hear the rumours.
"To be honest, I am quite surprised to hear rumours that I am quitting the show and not there on time when I am always first one to arrive. Strange na," she posted on her Twitter page.
There were reports that the "Veer Zaara" star was getting replaced after she was missing from an episode, which was judged by choreographer- director Remo D'Souza along with show's regular mentors Marzi Pastonji and Chetan Bhagat.
The reality show took off with 11 celebrity couples and is now left with seven pairs of TV stars.
