That demonstrated qualities in one area of life directly translate to desirability in another area is part of the Western myth of success. Beauty is social capital, and you cannot take ownership of someone else's social capital without an elaborate barter wherein wealth, intelligence, or power fill in the shortcomings of one's own beauty balance sheet. As an idea, there is nothing especially gendered about this, but in practice, and especially in America, it is men who seem most infatuated with this power dynamic.
In our celebrity culture, it is male celebrities who are far more likely to marry fans. Steve Jobs second wife was enamored of his early success with Apple while she was still a college student. Convinced they were destined to be together, she found a way to meet him and he soon after acquiesced to her fatalistic flattery. Kelly Preston grew up watching John Travolta in the Grease movies and was convinced it was her path in life to marry that man. When she reached Hollywood she created an occasion to introduce herself, and eventually they were married. Likewise, Corey Feldman's most recent wife (now divorced) first fell in love with the boy actor in Stand By Me and later chased him down in LA, where the couple married on a season finale of The Surreal Life. Even Priscilla Presley began as an adoring fan who convinced family friends to introduce her to Elvis, who she was sure would be the love of her life. It is hard to imagine an infatuated boy spending 10 years of his life building to a point where he could meet and seduce Ke$ha being greeted with the same openness.
The machinations of media and celebrity idolization are undergirded by the shadowy and aspirational idea that the universe give to men the gift of beauty in recognition of their intelligence, cleverness, and bravery. A woman being gifted with a beautiful partner is unfair, or at least so long as she's poor and unaccomplished. Minegishi is a hostage to this fantasy in her own way, repaid with fame and wealth for her willingness to stand in as a photoshopped, symmetrical ideal to keep a mass of boys yearning for romantic validation and intimacy that they seem to believe can only come through money and achievement.
