Deepika and Ranbir in another ad

"There's nothing intriguing about it. It's an ad to be directed by Imtiaz Ali for Pepsi. Earlier, Deepika and I acted in an ad with Shah Rukh Khan for the same brand. Now it's just the two of us, and that should be fun. But what I really want to do is a full-length feature film with Imtiaz," Ranbir told IANS.

Ranbir debuted with Sonam Kapoor in Sanjay Leela Bhansali's "Saawariya". Although the film didn't do well at the box office, Ranbir is inundated with offers. He is doing Yash Raj Films' "Bachna Ae Haseenon" and Rajkumar Santoshi has signed him for his forthcoming romantic film.

Sadly, just after cementing their relationship during the long outdoor spell of "Bachna Ae Haseenon" in Australia, Deepika, who had the privilege of working with Bollywood Badshah Shah Rukh in her very first film "Om Shanti Om", had to leave for a long shooting schedule for Nikhil Advani's "Chandni Chowk To China".

Hollywood studio Warner Bros is co-producing the action thriller with Ramesh Sippy. Akshay Kumar features as the male lead.

Deepika returned to India this week and is all set to start filming the ad with Ranbir. Deepika will team up with Saif Ali Khan later this year. Saif will produce the movie to be directed by Imtiaz Ali.

However, Ranbir's first cousin Kareena Kapoor, who is dating Saif, is not a part of Saif's first production. Apparently, Ali insisted on Deepika.
