Following reports in early March that the project would be called London Ishq, media outlets and social networking sites have in the past 24 hours reported that the film's name is Yeh Kahan Aa Gaye Hum.
Denying, however, that the movie has been given the title, an official from Yash Raj Films told Sawf News: "No, the film is yet untitled."
The rumoured name came from a song lyric in Yash Chopra's 1981 release Silsila.
Yeh Kahan Aa Gaye Hum had also been suggested as the name of the director's last film, which subsequently released as Veer-Zaara.
The spokesperson from the Andheri-based production company confirmed that Chopra is still in the process of making a decision on what his latest venture will be called.
The project, which also stars Anushka Sharma and Anupam Kher, had also previously been linked to the titles Hum London Mein Mile and Jai.
Speaking about the London Ishq rumour, Kaif told Digital Spy earlier this year: "It's a nice name, but inappropriate for this film and definitely not the name. That won't be the name."
Yash Raj Films' untitled film is expected to release in November.
