Why They're Hot: A few of South Korea's appropriately named Wonder Girls have already reached our legal drinking age. So what? Before the group's SoHee and HyeLim celebrate their 21st b'days, the quintet -- whose 2009 debut U.S. single "Nobody" made them the first Korean group to crack the Billboard Hot 100 -- will have dropped their first English-language album (scheduled for release in Jan. 2011) and saturated our airwaves with their infectious pop harmonies. We'll drink to that.
