On the IMDb a poster In_theatres has a post in her section and Points Out that Brooke Shields has had 2 or 3 nose jobs since she was a young teenager.He shows before and after pictures and it's very clear. They showed this TMZ a few years ago to with a before and after picture of her at 16 and the present.And on other celebrity plastic surgery sites.

And on another blog in 2007 when she was on Life Magazines cover someone asked why does her nose look Michael Jacksony? She had a small pretty shaped nose before she didn't need a nose job at all and now as some other people point
out her nose is too small for her face.
Look how different and much less smaller her nose was here at about age 13,

She also admitted she had Botox a few years ago too.

I completely agree. Her face during her youth was the face of an angel. God definitely took his time on her. She's still beautiful today, but obviously, everyone's looks fade due to the aging process.
