Priyanka rubbished it saying that when people see them together promoting the film, then they would get to know of such reports not being true.
Priyanka will be playing a dual role in the film, but she insists it's not a double role.
"I am not doing a double role but a dual role. I am playing Krrish's wife Priya Mehra as in the last film we left as being lovers. I go from being a good wife to being evil in the film. It is the duality of good and evil that I play which is very interesting," she said.
"When he (Rakesh Roshan) narrated me the script he was super excited about this thing. I had not decided or thought about this," she said.
Priyanka does not have any specific look in the film like her co-actress Kangana.
"There is Vivek's character that is bad and his army of mutants, they are called 'maanvar' which are a mix of human and animal. There is a chameleon girl played by Kangana, then there is scorpion, cheetah girl, rhino, frog man in it. They are in the army of 'Kaal' (played by Vivek Oberoi) and they are evil. I am normal, I am not part of the mutant space," she explains.
Sci-fi films are primarily about superhero and supervillian but in 'Krrish 3', both Priyanka and Kangana have interesting roles.
"Usually in superhero films girls don't have anything to do, they are just damsels in distress. But in this film, I have duality in the film and even Kangana's character is interesting," Priyanka added.
'Krrish 3' releases on November 1.
