Saif Ali Khan is on a new 'all time' high post the roaring success of his portrayal of Sartaj Singh in 'Sacred Games'.  He has wowed the audience as the tough Sikh officer who is constantly battling his mind and heart between what his duty demands and what is ethical.

Saif is known to be a very reserved person with a selected group of friends and even though he is a real life 'Nawab', his 48th birthday bash was a very private affair last night.

His kids, Sara Ali and Ibrahim joined the celebrations, though Taimur was missing from the pictures (the cute one anyway steals everyone's thunder!)

Kareena and Saif make a gorgeous couple and hence their pictures were nothing less than glamorous.
