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

Bollywood was in full attendance at a party to kick off the HDIL India Couture Week 2010 in Mumbai on Tuesday evening.

The five-day extravaganza will feature established designers, show directors, 36 female and 50 male models.

And of course, Bollywood showstoppers. 

Rani Mukerji, Shah Rukh Khan and Gauri add a splash of colour to the big bash, as they get ready to strut on the ramp.

Akshay Kumar lets his mega-watt smile do all the talking as he arrived with beautiful wife Twinkle by his side.

Looking their fashionable best are sisters Shilpa and Shamita Shetty. Even Shilpa's husband Raj Kundra looked dapper in a black suit.

Can't locate Vijay Mallya's son Siddharth? Just look out for Deepika Padukone. The two lovebirds are inseparable these days.

Favourite designer of the stars, Manish Malhotra arrived with two lovely women Urmila Matondkar and Sophie Choudry on each arm.

The designer, who was behind Aishwarya Rai Bachchan's eye-popping costumes in Endhiran/Robot, will showcase his bridal couture collection. It will, of course, be worn by Ash.

If in doubt, go with black, seems to be Anil Kapoor and Sameera Reddy's mantra when it comes to fashion.

No stranger to fashion, Mehr Jessia and husband Arjun Rampal looked tall and graceful as they pose for shutterbugs.

Mehr has choreographed designer Monisha Jaising's dramatic show which will wrap up the first day of the couture week.

Karan Johar keeps Sussanne Roshan company while Hrithik is nowhere to be seen.

The Arora sisters Malaika and Amrita keep Karisma Kapoor and Tusshar Kapoor company.

Goldie Behl and wife Sonali Bendre also made it to the party.
