Karan Johar recently started shooting for his much-anticipated film "Ae Dil Hai Mushkil" in London with lead actors Ranbir Kapoor and Anushka Sharma.

It has been reported that soon after the London shoot, the entire team will fly down to Vienna to film another portion of the Ranbir-Anushka-Aishwarya Rai Bachchan starrer, reported Mid Day.

Interestingly, Bollywood heartthrob Fawad Khan, who plays a cameo in the film, will join the team in Vienna. While details of the actor's character are not known, rumour has it that the actor will play the role of a DJ in the film.

Aishwarya, who will join the "Ae Dil Hai Mushkil" team in London after finishing her "Jazbaa" promotions, will also be part of the Vienna shoot.

If Aishwarya and Fawad shoot a sequence together, it would be a visual treat to viewers to see two good looking actors sharing screen space.

"Ae Dil Hai Mushkil" marks Karan's directorial venture after a gap of three years. The producer-director last helmed "Student of the Year" in 2012.

This is the second time Ranbir and Anushka are teaming up after "Bombay Velvet" that also had KJo. Aishwarya will be working with the team for the first time.

Produced under the banner of Dharma Productions, "Ae Dil Hai Mushkil" will reportedly feature Sunny Leone in a cameo role and is slated to be released in October 2016.
