She also teased that the "special" collaboration with her father will "take time".
"Never ever said anything about not wanting to do 'Aashiqui 3'! No idea where this is coming from," Alia tweeted in response to a tabloid which claimed the actress is sceptical about taking on the role.
Earlier, her "Student Of The Year" co-star Sidharth Malhotra had said he and Alia are waiting for "Aashiqui 3" to be put on paper.
"'Aashiqui' is a very special brand and working with my father for the first time is equally special! All things take their time. This will too," Alia tweeted on Friday.
