Karan Johan is a man well known for extravagant and lavish birthday parties filled with his celebrity friends. This year, marking his 45th birthday, was obviously no exception. With the likes of Abishek Bachchan, Aishwarya Rai Bachchan, Sidharth Malhotra, Katrina Kaif, Alia Bhatt, Varun Dhawan, Deepika Padukone, and of course, the three Khans: Shah Rukh, Aamir and Salman present at the party, it was, needless to say, a star-studded occasion. What's surprising was that Akshay Kumar and Twinkle Khanna attended the late-night party as well, contradicting to their 'early to bed, early to rise' style of living. Even more surprisingly, Karan's good friends Kareena Kapoor and Ranveer Singh didn't attend the party. It was surely a night of mysteries and excitement!
