Talent alone is not enough. Sleeping with your manager certainly helps.
It is naïve to think that nobody sleeps with their managers,
from various excerpts I gather
Also, why wouldn't people love them? Firstly, what we hear and read in the media are rumours anyway, we can't exactly say for sure who really used sexual favours to boost their career. What most people see is glamour and stardom. Secondly, forgive me for being rude, most fans (for example, Twins supporters) are very young, naïve and silly, IMO... They listen to the music, watch the soaps, buy everything... They love their idols not because of the idol's real personality (They don't know him/her personally) but because they believe in what they want to believe, i.e. they are buying an illusion.
Most of the actresses start off by going on dinner dates with managers etc to gain support and sponsorship.
