Wishing his fans for the upcoming Durga puja, actor Abhishek Bachchan Friday revealed that "nothing has been finalised" regarding the much-talked about film "Happy Anniversary", purported to bring wife Aishwarya Rai and him together on-screen.

In the city to launch eastern India's first Omega boutique, he cleared the air about "family friend" and celebrated adman Prahlad Kakkar's directorial venture.

"We have not read the script ... nothing has been finalised," he said.

Sporting the Seamaster Planet Ocean 600M GoodPlanet co-axial watch, the actor will be next seen in "Dhoom 3" with Katrina Kaif, Aamir Khan and Uday Chopra.

Abhishek will reprise his role of supercop Jai Dixit while Uday will yet again amuse audiences as his sidekick Ali in the third instalment of the "Dhoom" franchise, that started in 2004.

Unlike the previous two movies, which starred John Abraham and Hrithik Roshan as the bad guys, "Dhoom 3" has gone international with a larger plot.

Directed by Vijay Acharya, the film is scheduled for a Christmas release.
