Are women really that willing to sleep with celebrities?

Yes they are.
Men+power/money/fame=getting laid

Look at any fat ugly rich man or politician and they get laid.

Young American women grow up in a society where their value and self worth is measured in their looks and desirability. Having sex with someone famous is like a trophy that validates women, by telling them they are desirable. Some men also measure their self worth by how many women they can bang too, but they don't try to obtain famous and/or powerful women because that's an almost an unobtainable standard due to such a low avaliability. So they try a numbers game, sometimes not even worrying about the appearance of the woman. But if you asked any committed married man, if they would slept with a famous actress, model, or musician, they would definitely cheat too.

It depends on the woman of course, but your average woman would. Just like your average man wouldn't pass up the chance to have a one night stand with a female celebrity. I mean, if the celebrity is really ugly that might not be the case, but their being famous certainly would still work in their favor.

It's a common thing. be it random fangirls, expensive whores, or fellow celebrities....everyone has sex if fame is involved.

Yes. A group of my friends went backstage with LFO, a semi popular boy band and I didn't let my gf go with them which was a good choice.

unfortunately yes.... but it does depend on the girl. ive had a chance to cheat on a serious BF with someone semi famous and talented who had reputation and power but i opted out--- had he been MORE famous and powerful and i was more attracted to him, i hate to say it but i may have done it. but at the same time my BF and I were in a terrible place. shows how loyal i am. the time i could have slept with and actually dated, because he asked me to be his GF, a semi famous musician and opted out my BF was treating me like shi* but i am too loyal. but ill admit,its a thing. for women AND men. something about fame and power and status makes u want the validation from them. if you yourself are not famous or powerful.

this goes back centuries though. Kings had Mistresses. Even certain female royalty had side men. Musicians had groupies. Now actors have them too.
