Close friend Farah Khan hosted a party on the terrace of her Lokhandwala home and the do was attended by Sania's pals from Bollywood and sports.
Salman Khan, who is riding high on the success of Prem Ratan Dhan Payo, was among the guests.
Riteish and Genelia D'Souza came in together, so did Sushant Singh Rajput and his girlfriend Ankita Lokhande.
Sonu Sood drove in alone. Parineeti Chopra, a good friend of Sania, was one of the earliest guests to arrive.
Young filmmaker Punit Malhotra, who is fashion designer Manish Malhotra's nephew and Sonam Kapoor's ex-boyfriend, arrived with Tabu, who didn't seem too keen to pose for the cameras.
Actor Chunky Pandey, who is usually accompanied by wife Bhavna, attended the party alone. Neha Dhupia, who came dressed in a black number, looked pretty chilled out.
Tennis superstar Leander Paes, who was recently in news for his Grand Slam victory and also a bitter divorce battle with wife Rhea Pillai, was also spotted.
Farah's brother and filmmaker Sajid Khan was, obviously, among the invitees. Interestingly, his ex-flame, television actress Rakshanda Khan was also present at the do.
Celebrity photographer Avinash Gowariker -- he is director Ashutosh Gowariker's brother -- was accompanied by wife Shazia.

Because of the close friendship they share, there were rumours recently that Farah would make a biopic of Sania. However, while speaking to SpotboyE, she had vehemently denied them (I Am Not Making Any Biopic On Sania Mirza, Says Farah, August 6).
