150 Pop Stars' Real Names. You know them as Lady Gaga, Nicki Minaj and Sting. But these are the names on their birth certificates.



What's in a name? A lot, if you ask these musicians, each of whom ditched their birth names and adopted an alias before hitting the big time. (And for good reason, in some cases -- Ahmir-Khalib Thompson just doesn't roll off the tongue quite as easily as "Questlove," does it?) Check out the gallery and find out the real names behind 150 pop star pseudonyms. You'll never look at Robyn Fenty, Joel Zimmerman or Elizabeth Grant the same way.
