Lovebirds Ranbir Kapoor and Katrina Kaif apparently had a fight on the sets of their upcoming film "Jagga Jasoos" in South Africa. The reason for their fight is stated to be Kaif's "Bang Bang" co-star Hrithik Roshan.

According to Zoom, Kapoor is miffed with his girlfriend Kaif for comparing him to the "Krrish 3" actor Roshan.

Kaif and Roshan recently finished their month long action shoot in Abu Dhabi. After finishing the schedule for "Bang Bang," the actress flew down to South Africa to start the shoot of "Jagga Jasoos."

While shooting one of the action scenes on the sets, Kaif reportedly told him that Roshan did similar stunt in "Bang Bang." 

However, it is not clear whether Kaif praised Roshan for the stunt, which irked her current beau Kapoor. But Kapoor was reportedly angry with Kaif and had demanded apology from her. 

"Kapoor got so angry with this that he refused to work until Katrina apologised and promised to never ever compare him or make a similar comment about his work in future," India TV reports.

Post the separation of Roshan with his wife Sussanne, there were reports that bond between him and Kaif have strengthen. Their growing bond was clearly visible while shooting for their film in Manali. [Read the report here]

But its not only the "Bang Bang" lead actors, but Roshan and Kapoor also share really great bond.

Rishi Kapoor and Rakesh Roshan are really good friends and so are their sons. Roshan used to babysit Kapoor when he was 4-year-old and since then the two share a great friendship.

In fact, when Kapoor's first film "Saawariya" hit the screens, it was Roshan who called him first and congratulated.

"Hrithik and Ranbir have shared a great equation over the years and have been friends since their childhood. To date Hrithik calls Ranbir after every film to give him a feedback on his performances in films as well as his commercials," a source told Koimoi.com.
