Tusshar Kapoor is neck-deep in the promotion of his solo release, NR Pachisia's Kya Love Story Hai, co-starring Ayesha Takia and newcomer Karan. In fact, he is so busy that he's had to refuse Tigmanshu Dhulia's next film, starring Nana Patekar.

Says a source close to Tusshar, "Tigmanshu came to Tusshar with a script, which he loved, but he had to refuse as he has too much work. Currently, he's busy working on the promos and marketing of Kya Love Story Hai, as it's his solo release after a long time."

Apparently, Tusshar is extremely involved in the film. Says the source, "He is overseeing the publicity and design with director Lovely Singh, checking out promos, working on the overseas distribution with Studio 18 and generally sitting on the producer's head!

Kya Love Story Hai is neither a big film like Priyadarshan's Dhol (Tusshar's next project) nor is it a multi-starrer, so it requires extra attention, that's why Tusshar has decided to give it his undivided interest."

That's not all, adds the source. "There is a rock concert and a music video shoot of Apoorva Lakhia's Shootout At Lokhandwala coming up in April, which has all the stars in the film, and Tusshar has to prepare for that too."

Tusshar says, "Tigmanshu's script is very good and he's a great director, but I am busy with the promotions of Kya Love Story Hai, the Shoot Out rock concert and video, so I couldn't do his film. Kya Love Story Hai is a very important film for me and is very close to my heart.

At the moment, I am extremely tied up with it. But I am sure Tigmanshu and I will work together in the future again."
