>>212557043 (OP)Ultimately the same thing that happened to almost every busty star who gets fame for being 30 years old with a huge rack. Eventually they all hit 40, their career lulls and they're never quite able to get the "mom" roles while they age out of the sexpot roles.
Jayne Mansfield and Marilyn Monroe were some of the originals, but overall you either die or disappear. It's a bit of a tragedy, but you don't see too many Scarlett Johansen's and in some ways Scarlett was benefitted from being a Child Star whose mom was a producer who developed into a slender busty woman. She wasn't from some Pacific Northwest shithole just happy to be here or plucked out of a factory line by a cameraman for her smile. She was a nepobaby who worked her way up to the top of the food chain from a preferable position.
Sweeney will wane like most do, she'll show a few smile cracks or some crows feet and some new sexy blonde bombshell at 25 will take America by storm.
