The Billboard Music Awards will feature several artists who tore up the charts this year -- including Ke$ha, Nicki Minaj, Taio Cruz and Justin Bieber -- all up for top new artist honors at this year's show, according to a special awards edition of Billboard Magazine.

The issue, which is only available to Billboard subscribers, features the up-and-coming stars sharing their experiences of sudden fame. Ke$ha told the magazine she only experienced her first groupie recently.

Looking back at her incredible year, Ke$ha still can't believe her good fortune. "Are you kidding?" she says, when asked if she's come to terms with her newfound superstardom. "I'm not used to any of this yet." Then, for effect, she adds, "I just had my first groupie last night!" Okay, so don't forget everything you think you know about Ke$ha.
