Some actresses doesn't like the word item and try to call them special songs, that they do in a movie.
Any actress who is not a heroine but shakes her leg with the hero and other important characters in a song that is completely there to stale the story but provide some entertainment to viewers is called "Item Song" or "Special Song" and the actress is called "Item Girl".
Such songs are common in Telugu Cinema and they are known as pre-climax songs.
Big actresses started doing such special or item songs in 90's and it has become a norm that big movies have such songs for sure.
In big films, famous star heroines appear in those songs and now, Shruthi Haasan is ready to do such item numbers too. She doesn't have many film offers from South Indian Cinema.
Hence, the actress is looking at doing special or item songs in Big movies to not let the audience forget her. She herself took a break from movies for other works but as they are also delayed and she doesn't want to give 40 to 50 days as dates, simple special songs that needs two to three days looks lucrative for her, it seems.
