Luscious Lindsay's boobs are 99% real. From very close up HQ inspection, she is a 32C. She is very thin, that is why I think she is carrying such enormous breasts for a beauty of her height and weight. Obviously plastic surgeons have refined their technique so beautifully, that the look of Lindsay's mammaries are so eye poppingly sensational.
It is also reasonable to assume that she knew fully that those pics would be taken and she wanted her adoring fans to see that she still has what it takes to drive us all crazy with wanting to see her every move. Lindsay knows that the more she shows, the more we want of her.
