A while back, it was white girls (though I guess that never really went away). Around the early 90s, it was green eyed black girls. Around the late 90s it was Chinese or Filipino girls. I believe the next US urban/hip-hop fad will be an Indian girl as your side.
With the mainstream popularity of Aishwarya Rai and that Bend it like Beckham girl on TV, Indian girls are going to be all over. This is not a derogatory chauvinistic thing, just a social observation/commentary.
Aishwarya is very pretty, but here are some other to get familiar with whom are very attractive.
