Selena Gomez went from Barney to Bieber in only a few short years. While she's now known for her sweet-and-sultry pop songs, the "Love You Like a Love Song" star got her start parading around with a purple dinosaur and entertaining kids on the Disney channel.
Pals with Demi Lovato and the former girlfriend of heartthrobs Nick Jonas and Taylor Lautner, the Wizards of Waverly Place beauty is used to making tweens green with envy.
But nothing compares with the madness that surrounded her dating Justin Bieber. Frequent tweeted death threats from Bieber's fans had Gomez considering deleting her account.
Of course, hate-tweets from Beliebers are only part of Selena Gomez's problems. The Hotel Transylvania starlet had to obtain a restraining order against one of her own obsessed fans in 2011 after he claimed to have had over 50 conversations a day with God about killing the singer.
Later that year, the Spring Breakers star incurred the wrath of both PETA and Pink, who accused her of animal cruelty for using horses painted pink in her "Love You Like a Love Song," video.
In the end, Gomez ditched the pretty pink ponies and has largely avoided controversy since.
