Reality TV show: American Idol (2004)
Beyoncé, mother of Jay-Z's child and 16-time Grammy Award winner, is a nearly impossible woman to upstage. Nearly. In 2006, an American Idol finalist by the name of Jennifer Hudson was plucked from post-reality obscurity and cast alongside her in a big screen adaptation of Broadway's Dreamgirls, Hudson's very first acting role.
To say that she stole the show would be an understatement—mountains moved, seas parted, and grown men bawled like babies after she brought houses down worldwide with her rendition of "And I Am Telling You." Hudson was presented the Academy Award for Best Supporting Actress, and the movie, music, and endorsement offers only continued to flow in.
