The 26-year-old actress, who is the cover star of this month's Esquire Magazine, wears a slinky black underwear set with an unbuttoned, pointless shirt in the shoot, the Mirror reported.

She told the Mirror last month: "It changes your perspective about being overly sexual in a film when you have a baby."

"I'm going to be more cautious about choosing films because I'm already thinking about when he's in school and his friends are going to be showing him my photoshoots with me in a bikini and he's going to be horrified."

"So that will deter me from making some of the choices I made before," she said then.

Poonam Pandey, who has always maintained a size zero figure, has decided to shed this image soon and gain some extra weight for her Bollywood debut.
