'It's gonna be hard taking the Biebs down,' the 'Tik Tok' singer tells MTV News about her Best New Artist nom.

Ke$ha will storm this September's Video Music Awards with four nominations — she picked up three for her infectious breakthrough single "Tik Tok," as well as one for "My First Kiss," her duet with 3Oh!3. But the singer isn't quite sure she'll be able to wrest the Best New Artist Moonman from windswept heartthrob Justin Bieber.

"It's gonna be hard taking the Biebs down," she told MTV News. "It's gonna be hard, but my fans — we can do it!"

Justin Bieber isn't Ke$ha's only stiff competition on September 12; the brash singer is also up for Best Female Video against heavy hitters like Lady Gaga, Beyoncé and Taylor Swift. But she hopes that her fans will party all over the ballot box and sweep her to victory.

"I have no idea! Gaga and Beyoncé and Taylor Swift — everybody in there I respect, so it's kind of like I have no disses to throw," she said. "That's a tough category. ['Tik Tok'] was my first video, so that really is exciting. I had no idea what I was doing. It was my first time making a video, so it's really kind of cool. I'm excited to see if I and a chance, but I think we can take them. Can't we? I'm down to try!"
