Alia, 22, said she will approach "Shuddhi", which was announced in early 2014, like any other project.
The film, to be produced by Johar and directed by "Agneepath" helmer Karan Malhotra, originally had Kareena Kapoor and Hrithik as the lead pair.
But it got derailed due to Hrithik's health issues leading to his exit following which Kareena also walked out. Later, Salman Khan was roped in but his leading lady was undecided. After some time, Salman also opted out.
This is the third time she will be teaming up with Varun after "Student of the Year" and "Humpty Sharma ki Dulhaniya".

"I am not sitting... Taking a backseat and thinking I have achieved something. I don't feel I have achieved anything. I feel I have a long long way to go. I have just started. More than being content I am excited, energetic and nervous to do more good films," Alia said.
