Lil Kim seems have had the plastic surgery when she was in jail. She looks awful with it. The brow lift is more than comfort may be due to endoscopic browlift, her nose has been whittled down to become Jackson-esque, and her cheeks look like that of a blowfish.
(this is her "before" pic)She appears to have had either excessive fat grafting or massive cheek implants, placed by a cosmetic surgeon who either didn't know what he or she was doing, or unfortunately didn't care. She used to be beautiful once. Now she appears to me to be a nice case of Plastic Surgery gone Wrong of a plastic surgery addict.
Have a look at her recent pics:
Now have a look at this one, it's awful.
