Filmmaker Karan Johar is making his directorial comeback after three years with "Ae Dil Hai Mushkil." He revealed the names of Aishwarya Rai Bachchan and Fawad Khan's characters at a recent Twitter interaction with fans.

Fawad, who is reportedly playing a hot DJ in the film, will be called Ali, while name of Aishwarya's character is Saba Taliyarkhan. The former Miss World reportedly plays Ranbir Kapoor's love interest in the film, as "Ae Dil Hai Mushkil" is about a man falling for an older woman older.

A few days ago, Fawad revealed his character, which was earlier expected to be a cameo, is actually the backbone of the story. "It's not exactly a cameo but it becomes the backbone of a certain conflict of a character in the movie. It's like 15-20 days of work. My role is that of a DJ. So it's cool. I have tried something new altogether, I am wearing a completely new costume. I wouldn't mind playing a cool-guy character or a complete buffoon as well," Fawad told the Press Trust of India.

On the other hand, there were reports that Karan's lucky charm and good friend Kajol would do a cameo in "Ae Dil Hai Mushkil." But, KJo denied the reports during his Twitter chat.

Scheduled to be released Oct. 28, "Ae Dil Hai Mushkil" is being touted as a complicated love story produced by Dharma Productions. Apart from Ranbir and Anushka Sharma's romance, the audience will also see Ranbir and Aishwarya's chemistry.

Meanwhile, Pakistani heartthrob Fawad is busy promoting his upcoming film "Kapoor and Sons," while Aishwarya is shooting for Omung Kumar's "Sarbjit." Ranbir is working on Anurag Basu's "Jagga Jasoos" alongside ex-girlfriend Katrina Kaif, and Anushka is shooting for "Sultan" opposite Salman Khan.
