Director-producer Karan Johar celebrated his 44th birthday on May 25 with his B-Town friends in London. The filmmaker shared several pictures of his rocking bash, and celebs like Shah Rukh Khan, Ranbir Kapoor, Sidharth Malhotra and Kareena Kapoor Khan were seen with the birthday boy in the photos.

SRK and Gauri Khan along with AbRam and Aryan attended the birthday bash. In fact, Navya Naveli and her mother Shweta Bachchan Nanda were also spotted at the bash. Aryan and Navya have recently graduated from Seven Oaks School in London. Thus, the kids and their parents could make it to KJo's party that was held in the same city.

It had been reported that ex-couple Ranbir and Katrina Kaif were in Morocco for "Jagga Jasoos" and went to London after wrapping up shooting, but only Ranbir could be seen in the pictures. Also, Kareena and Saif Ali Khan attended the bash as they were already in London on vacation. Sidharth and Alia Bhatt were also invited, but the "Udta Punjab" actress gave it a miss due to a film shoot.

As London is Karan's favourite place, he had celebrated his last birthday in the beautiful city. In fact, his upcoming film "Ae Dil Hai Mushkil" has been shot in the British capital. KJo is making his directorial comeback after three years with "Ae Dil Hai Mushkil," which features Ranbir, Anushka Sharma, Aishwarya Rai Bachchan and Fawad Khan in key roles.

Check out some amazing photos of Karan's birthday bash. The filmmaker has shared quite a few pictures from the occasion on his Instagram account. Take a look here:
