The story about the boob job is unclear.
Its says her grandparents loaned Amy the money. But says she also asked for the boobs as a birthday present.
It was quite a few years ago and she still hasnt paid them it all back.
No mention of her parents not affording it.
Pagents are not cheap to enter and participate in. Given their back grounds and what people who know then have said, I doubt they arent well off.
But yea, it doesnt mean they paid for her to get in either.
