Hrithik Roshan celebrated his 37th birthday on January 10 by throwing a party in Mumbai that night.

Close friends and colleagues were among the invitees.

In the picture: Kangna Ranaut and Shah Rukh Khan.

Shilpa Shetty came with husband Raj Kundra and sister Shamita.

Glowing mummies Karisma Kapoor and Amrita Arora came minus their babies.

Twinkle Khanna turned up as well but minus husband Akshay Kumar.

Katrina Kaif is obviously in a party mood. After attending Imran Khan's pre-wedding bash in Karjat, she partied with Hrithik on his birthday.

Bipasha Basu arrived with designer Rocky S. The actress' boyfriend John Abraham, however, was nowhere in sight.

Others spotted at the party were Kunal Kapoor, Dino Morea, the Akhtars and the Rampals.
