Vidya Balan, who will be seen in a sleazy avatar in Ekta Kapoor's Dirty Picture, will use butt-pads to get a well-rounded bum. Ekta apparently wants a 'fuller' look for the Ishqiya actress in the Silk Smitha biopic.

Vidya is playing south siren Silk Smitha's character in the film which required her to gain weight. While the buzz was doing round that actress will have to use prosthetics to increase her bust line, now she will have to follow her once 'special friend' Shahid Kapoor's footsteps and go for butt-pads to get a bulky look for her hips as well, reported Mumbai Mirror. Producer Ekta has made AD Shahana and make-up artist Vikram Dada in charge of her Silk Smitha look, reportedly. The movie is scheduled for a November release.
