These are NOT professional pics. She posted them on Twitter and the pics are not PB's property.
The Indian actress herself admitted they were hers and she seems to have enjoyed them... Well, it's causing some furor back in India (expected). But I'd say, well done for daring to bare!
Btw, I think it could be a shooting with a strong ethnic accent!
She's got bigger boobs than I thought. I'd pass on the pics to my Indian colleagues in London. Guess they've seen it too.
