Here's what your favourite celebrities have been up to.

Sonam Kapoor, the lead star of the movie, Aisha, is spotted at the film's premiere in Mumbai on Thursday night.

The film opens today (read the review here).

Also spotted at the premiere is Sonam's father Anil Kapoor along with the film's cast member Lisa Haydon.

Elsewhere in Mumbai, Salman Khan threw a belated birthday party at a suburban night club on Thursday, to celebrate his brother Arbaaz (August 4) and sister Arpita's (August 3) birthdays.

We caught a glimpse of Salman, who is sporting a moustache for his latest movie, Dabangg.

Salman celebrates his younger sister Arpita's birthday every year. This year the party was delayed as some of Arpita's close friends were out of town.  

The guest lists was a varied and interesting mix of people. Speaking of which, we spotted Salman's ex, Sangeeta Bijlani at the party minus cricketer husband Mohammad Azahruddin. Their marriage was recently in trouble when it emerged that Azharuddin was involved in an alleged affair with badminton player Jwala Gutta. 

Another interesting sight was that of Deepika Padukone whose date is none other than Siddharth Mallya, the heir of the UB group and the scion of business tycoon Vijay Mallya.

Katrina Kaif's lookalike Zarine Khan looks ravishing in blue as she arrives for the party.

Salman's family was also in attendance. Spotted here is Salman's stepmom Helen and brother Sohail Khan.

Birthday boy Arbaaz came with his wife, Malaika Arora Khan.

Brother and sister duo Ashmit and Amisha Patel also made it to the party.

Others who attended the party included Harman Baweja, Prateik Babbar, Farah Khan, Sajid Khan, Sajid Nadiadwala, Riteish Deshmukh, and Dabangg heroine Sonakshi with her parents Shatrughan and Poonam Sinha and brother Luv.

Meanwhile, Neil Nitin Mukesh poses for shutterbugs during the launch of Hi Blitz magazine.

Here's a chance to hang out with him and his Lafange Parindey co-star Deepika Padukone.
