Jacqueline, Kat, Sonakshi, Farhan join Sidharth in his birthday revelries

Jacqueline, who's set to be Sid's next co-star in 'Reload,' and also is his rumoured flame currently, was her buoyant self.

Ritesh Sidhwani, who co-produced Sid's 'Baar Baar Dekho,' was accompanied by his wife Dolly Sidhwani at the do.

Though, Ritesh was quite cheerful, his partner Farhan Akhtar seemed to be in the mood to brood.

Sister Zoya Akhtar seemed to be in no mood to smile for the shutterbugs, either.

His co-star from the film, 'Katrina Kaif,' looked as angelic as ever.

Sanjay Kapoor, who was last seen in 'Shaandaar,' looked dashing having dressed to kill.

Parineeti Chopra, who's been on a long sabbatical from the big-screen, glowed and looked gorgeous as ever.

Raveena Tandon, who'll be soon seen in the film, 'The Mother,' looked every bit the diva she was, back in the 90's.

Imran Khan, who was last seen in the Kangana Ranaut starrer 'Katti Batii,' was flanked by his wife Avantika Malik.

Manish Malhotra flashed his infectious smile, as the shutterbugs went on an overdrive spotting him.

Ayan Mukherji, who's gearing up for his upcoming superhero flick, 'Dragon,' starring Ranbir Kapoor and Alia Bhatt, seemed quite excited about the bash.

Sonakshi Sinha, who was last seen in Abhinay Deo's 'Force 2,' was uncharacteristically shy of facing the media.
