Mumbai, Feb 24: All the Himmatwalas came together at the launch of the retro peppy number, "Thank God Its Friday' at a posh lounge in Bandra.Dressed to the T in a retro outfit reminiscent of the one Parveen Babi wore in Shaan's cult hit 'Pyaar Karne Waale', complete with a thin metal headband and chunky ring, Sonakshi stuck to a few choreographed moves before leaving the stage to the background dancers. Director of the flick Sajid Khan says that Sonakshi Sinha was his first and last choice for the song."Sonakshi was my first and last choice for the song. I had decided that if she doesn't say yes, I'll drop the song," he said at the launch of the song held here Friday evening.Sonakshi has donned two looks in the song. The first one has been inspired from Parveen Babi's look in "Shaan" and the second one is similar to Sridevi from "Chaalbaaz".Sonakshi was recently also seen in the song "Go Go Govinda" from the film, "Oh My God". Asked if the actress was planning to become a queen of item songs, she said that the song had to be special for her to be a part of it."I like dancing but the song has to be special for me to be a part of it. Even 'Go Go Govinda' had something special and so does 'Thank God Its Friday'," she said.The actress also added that she didn't have to put in much preparation for the song."I just reached the sets. I did not do any kind of preparation. I have seen these songs before. People say I have the old world charm and I used that," she said.Directed by Sajid Khan, "Himmatwala" stars Ajay Devgn and Tamannaah and is all set to release on March 29.
