Celeste was never a naturally beautiful woman. She was at best the girl next door hot.
She went the route of enhancements, fake tits, juiced physique, facial fillers, botox, hair extensions, lip injections etc
Probably had some health issues so dropped all those poisons and went "natural". She made a right choice to age naturally IMO. Stay on that "fake" path too long and you'll end up looking like a gargoyle like Madonna or that slutty female who was doing cartwheels for ARod
