Item numbers in Bollywood movies - what are they really? Are they the last desperate attempt to save an unglamourous movie? Sometimes. Are they an easy way to attach a famous star or a Size 0 model to a movie with a relatively new cast? Sometimes. Do they have any significance in the plot of the movie? Very rarely. And yet, here's one that does. Richa Chadda, famous for her role in Masaan, is starring in Pooja Bhatt's Cabaret and redefining what it takes to make a hit song. Her role is glam, bold and extremely sensual - and it's just amazing to see someone looking like she's having a blast as she dances away. We can't wait to see her do justice to the role - yes, we've already made up our minds that she'll live up to our expectations of this movie.
