On Ranbir Kapoor's 32nd birthday, his alleged girlfriend Katrina Kaif reportedly threw a surprise birthday bash for the "Besharam" actor.

Attended by close friends and family, the party was held at "Yeh Jawaani Hai Deewani" director Ayan Mukherji's house.

"Katrina was planning this party with Ayan Mukherji since a long time. It's Ranbir's birthday and she wanted to make it special for him. Accordingly, she planned a quiet, cosy dinner with their close friends," and source told Mid-Day, "She was already in touch with Ranbir's close friends, including Rohit Dhawan and a couple of Ranbir's school friends. Ranbir was thrilled to catch up with them over this surprise dinner."

Kaif, despite being on her toes for "Bang Bang" promotions, found time to arrange a surprise for birthday boy Kapoor.

"Katrina was busy promoting Bang Bang but she made time to plan a perfect birthday party for her boyfriend Ranbir. Since Ayan is a common close friend, she roped him in and reached out to their close friends who then came calling later on Sunday evening. In fact, the party was held at Ayan's house," added the source.

From being spotted on romantic get-aways, to calling the "Barfi" her 'soulmate', Kaif has given her fans enough reasons to believe that her rumoured relationship with the Kapoor scion is true to a certain extent.

Praising Kapoor's loyalty, the gorgeous actress had told The Times of India that the actor for sure has more to him than what people get to see.

"Ranbir is like me, in the way that he is very loyal and emotional to the people he really cares about in his inner circle, which is very small. He can come out very detached to people outside of that," she said.

While Kaif will be next seen in "Bang Bang", Kapoor is set to charm the audience in Imitiaz Ali's "Tamasha" opposite ex-girlfriend Deepika Padukone.
