Sunny Leone, no doubt, has become a popular Bollywood actresses with back-to-back film offers, but the former adult star never got a chance to work with B-Town's A-listed actors until recently.

After being approached by Akshay Kumar starrer "Singh is Bling", Sunny has now been roped in by popular Bollywood filmmaker-producer Karan Johar for his next directorial venture.

Sunny will reportedly make a special appearance in KJo's "Ae Dil Hai Mushkil" starring Aishwarya Rai Bachchan, Ranbir Kapoor and Anushka Sharma.

"It's been Sunny's dream to be cast opposite A-List heroes and banners. But the dream came true only recently when Akshay Kumar got her to do a cameo in his home production Singh Is Bliing And now she will be sharing screen space with Ranbir!" a source told DNA.

"Karan Johar also got Rakhi Sawant on his show Koffee With Karan, so he doesn't have snob value. He understands that Sunny is a huge draw at the box office. He approached her for her oomph factor that are a big draw for audiences in the interiors. The actress is thrilled because this means that slowly and surely she is moving into a bigger league," the source added.

It would be interesting to see the "Jazbaa" actress, Ranbir and Anushka sharing screen space with the "Baby Doll" star.

Meanwhile, the plot of "Ae Dil Hai Mushkil" is said to be partially inspired by Rishi Kapoor, Raakhee and Neetu Singh's "Doosra Aadmi" (1977). Apparently, Aishwarya will play Saif Ali Khan's wife, while Ranbir and Anushka are expected to essay the role of lovers.
