Karan Johar celebrated his 44th birthday in London with his close friends from the film industry.

The maverick filmmaker hosted a private bash which was attended by Shah Rukh Khan, Ranbir Kapoor, Sidharth Malhotra, Kareena Kapoor Khan and few others.

Johar's favourite boy, AbRam, was also present!

Take a look.

Perpetual pouters: Kareena Kapoor Khan and birthday boy Karan Johar.

The three musketeers: KJo, Aryan and Shah Rukh Khan.

Karan got all nostalgic as he shared this picture on Instagram. He captioned it, "When you feel older and prouder at the same time....kids are a strong reminder of how time flies...#AboutLastNight."

Upping the glamour quotient at Karan's party were the gorgeous Shweta Nanda and her stunning daughter Navya Naveli Nanda.
