Guess who are the newfound BFFs in Bollywood? It’s actor Sanjay Dutt and casanova Ranbir Kapoor. Sanjay has been keen to work with Ranbir for a while. But recently he went as far as buying RK junior a three million Indian rupees bike for his birthday. Apparently, Sanjay wanted to cast Ranbir in his father Sunil Dutt’s role in the remake of ‘Mujhe Jeene Do’. He has also expressed his fondness for the junior Kapoor. But it seems Sanju is way too full of love for him, so much so that he gave him a rather swanky birthday present. Ranbir had no such plans to celebrate his birthday but Ashtavinayak, the producer of his forthcoming film,‘Rockstar’, threw him a surprise bash. A lot of Bollywood actors graced the surprise birthday party by making it to the night spot in Juhu. Sanjubaba not only dropped by at the surprise party but also bought him a bike. A source informed, “Dutt has seen Ranbir grow up. They work out together at the same gym. Though Ranbir has his own trainer, he had always looked up to Sanju. When it came to buying a gift for Ranbir, Dutt immediately thought of a bike. Sanju knows how much Ranbir loves bikes.”
