Aishwarya Rai Bachchan at Cannes, 2011

Remember the awesomeness that Ash was at Cannes? The actress looke and moved like a dream at the biggest film festival in the world and was even feted as one of the best dressed attendees.

This particular hairstyle saw her veer away from her play-safe mode as she went for a tight-upswept do and pulled it off.

Deepika Padukone was all about Indian charm in a Rohit Bal sari when she turned up for the premiere of a film at last year's Cannes Film Festival.

The actress went for a chic soft bun that beautifully complemented her Indian look without being too ethnic.

Sonam Kapoor dazzled all with her haut-couture hotness in a Jean Paul Gaultier gown. Her Grecian updo with soft curls made her look even more dreamy.

Priyanka tried out something new when she appeared for the screening of her film What's Your Rashee at the Toronto Film Festival.

Only the dress, like the film, failed to do any wonders for her. And what was she thinking pairing that hairdo with that outfit?

Back when Shilpa was hot property in Britain, the actress attended the photocall of the film Miss Bollywood - The Musical in London wearing this rather fetching headgear.

Hope she didn't break into a samba dance routine.
