Yesterday, Karan Johar hosted his 45th Birthday party and it a starry night. All Bollywood celebs were present there including Shahrukh, Akshay Kumar, Aditi Rao Hydari and many more. Katrina Kaif and her ex boyfriend Ranbir Kapoor was also present and bumped into each other. According to the reports of Pinkvilla:

"Katrina Kaif joined Ranbir Kapoor, Aditya Roy Kapur and Anushka Sharma and they all sat together and chatted the night away. Surprisingly, both Ranbir and Katrina looked very comfortable together and surprised the people around them. In fact, there were many other actresses with whom RK shares a great equation. But he kept his interaction with them minimal and was instead sitting and conversing with Katrina, Anushka and Aditya."
