Sidharth Malhotra cannot wait to start shooting with actress Katrina Kaif for his next film, which he says is a light-hearted, unique love story.

The film, apparently titled 'Kal Jisne Dekha', will go on floors this week and will be shot mainly in the UK.

The 30-year-old actor, who is sharing screen space with Katrina, 32, for the first time, said the movie will have them play different ages.

"I am going to start shooting with Katrina for a love story next week. We will be shooting this film in the UK. It is a unique love story of these two people who span over a period of time. It gives us a chance to play different ages, there is an X-factor in it," Sidharth told PTI.

Riding high on the success of his action-drama 'Brothers', Sidharth is happy his next project is a love story.

"We both are preparing for the role, we have been doing rehearsals. we are really excited to start shooting. I am quite excited to share screen space with Katrina. It will be a lot of fun, it is a lighter love story. It is not on a serious note," he said.
