Apparently, Bollywood actor Ranbir Kapoor bonded so well with model-turned-actor and now National Award winner for his performance in 'Rock On', Arjun Rampal, on the sets of 'Raajneeti' that he consider Arjun his "brother for life" now.

Ranbir revealed about his new brother Arjun while addressing a press conference at the Galaxy Hotel in Mumbai recently.

"I have had a wonderful time working with Arjun in 'Raajneeti'. He is my brother for life. I love him a lot," said Ranbir.

"In fact I love him so much, so much that I am jealous that Mehr is his wife," Ranbir quipped.

Reportedly, Ranbir and Arjun formed a friendship immediately after meeting on the sets of their forthcoming movie 'Raajneeti' that also features Katrina Kaif, Nana Patekar, Ajay Devgan, Manoj Bajpai, and Naseeruddin Shah in important roles.

Arjun too considers Ranbir his dear friend and brother

Even Arjun gladly admitted that he thinks of Ranbir as his younger brother and also went on to praise other stars in 'Raajneeti.'

"I have found a good friend in Prakash, guide in Nana (Patekar) sir, enemy in Manoj (Bajpai), a younger brother in Ranbir and Katrina has been a wonderful person who lets me pull her leg," said Arjun.

Ranbir and Arjun scared Katrina with their pranks?
Reportedly, after becoming good friends, Ranbir and Arjun left no opportunity to play prank on their ‘Raajneeti’ co-star Katrina Kaif.

However, Ranbir denied the report saying that, "We didn’t terrorize Katrina; in fact, she terrorized us."

Once an incident happened on sets where tadka dal they did not order showed up. Probably, Katrina had ordered the dal and upon not finding the dish there she started asking -- "Where is the yellow sauce?"

"All of us were taken aback, and began looking for 'yellow sauce,' said Ranbir. After asking Katrina for some more explanation on the elusive 'yellow sauce' she revealed that "she’s talking about "the yellow sauce, which is eaten with chapatti" then we understood and had a good laugh," added the actor.
