Make that the blue carpet!

Forget about Simon Cowell and L.A. Reid -- it was ALL about Britney Spears and Demi Lovato at the Los Angeles premiere of The X Factor on Tuesday evening. The ladies posed for photos at Grauman's Chinese Theater on Hollywood Boulevard, and Brit tweeted, "I'm here!!! Just walked the blue carpet for the #XFactorParty - so exciting!"

The foursome were also honored with a Walk of Fame handprint ceremony, and they chatted with reporters about returning next season. "Of course I'd hope to be on it for more," Lovato told E! Online. "This show has been so incredible. The best experience of my life. I can only hope for another season." Spears added, "It's a possibility, definitely," and when asked who's the tougher judge, the singer thought for a moment and said, "I think Demi. She's a little bit younger than me. She's a spitfire." Demi's response? "I am a bit of a spitfire," she said. "That wouldn't be the first time I've been called that."
