Today on Twitter, all the biggest pop stars were talking about Halloween! Nicki Minaj sent her love to everyone dressing in her likeness this holiday, while Kesha asked her "animals" to send pics of their costumes. Danny O'Donoghue of The Script posted a picture of his Edward Scissorhands costume and we must admit, he looks just like Johnny Depp's character from Tim Burton's 1990 movie. Joe Jonas was encouraging his followers to take candy from strangers and Crystal Bowersox was going to use her son's treats in her mothering negotiations! Keri Hilson was keeping it low key this year while Hayley Williams of Paramore thought people look more like themselves on the spooky holiday. Adam Levine teased his costume included bike shorts (Lance Armstrong, perhaps?), but the best were the 'Mylo Xyloto' jack-o'-lanterns Coldplay tweeted! See what your favorite stars were chirping about today!
