Bollywood heartthrob Ranbir Kapoor, who is busy with his next project "Jagga Jasoos" which co-stars his alleged girlfriend Katrina Kaif, will reportedly play a teenager in the film.

The 32-year-old, who is supposedly dating Kaif, will reportedly play a 19-year-old in "Jagga Jasoos", while Kaif will portray the role of a 22-year-old.

Both lead stars, who will be seen playing young characters in the film, have given special attention on their looks and make-up, to make them look much younger than their actual age.

"For the portions that have been shot so far, Ranbir will be seen playing a teenager, while co-star Katrina Kaif, 30, will be seen portraying a 22-year-old girl in the film. Their makeup and look has been designed as per the role requirement," a source told The Times of India.

With the alleged lovebirds portraying different looks in the film, it will definitely be a visual treat to the fans.

"Jagga Jasoos" is being helmed by director Anurag Basu of "Barfi" fame, and apparently has Govinda in Kapoor's father role. There have also been rumours that Govinda has been replaced by Jackie Shroff. However, no further reports are available, regarding the change in the cast.

The film has already completed the first schedule shoot in Cape Town, South Africa. The remaining portions will be shot in Mumbai, followed by Manipur and Thailand.

"Jagga Jasoos" is a detective drama, which revolves around father-son relationship, and will hit the screens on 29 May 2015.

Meanwhile, the "Barfi" star, who has no releases this year, will appear in two big budget films next year. The actor will be seen in Anurag Kashyap's "Bombay Velvet", opposite Anushka Sharma, which is slated to hit the theatres early next year, which will be followed by "Jagga Jasoos".
