After months of rumors and speculation, an alleged fight, and walk-offs, it was finally time to see what Britney Spears and Demi Lovato could do as judges on the Season 2 premiere of The X Factor!

And surprisingly (or not surprisingly), they were both solid on opening night! There was no real drama at the judging table -- every contestant Demi thought was good or bad, Britney agreed with and vice versa. The main difference came in how they delivered the crippling blow of rejection to certain contestants. Who knew that Britney had a little Simon Cowell in her?!

Demi seemed to take the nicer approach when it came to rejecting contestants. When 50-year-old Shawn Armenta put on a bomb of an audition, Demi told him that, "A lot of people work really, really hard for their dreams, but it's not meant for everybody." Shawn took the constructive criticism by insulting Demi's singing ability and Britney immediately turned into the female Simon. "I want to know who let you on stage," she said. "I feel uncomfortable with you just staring at me."Ouch!

Some of Britney's other top lines of the night? "I felt I was listening to Alvin and the Chipmunks," she told one reject. Moments later, she bashed another aspiring pop star's audition by saying that, ""I feel like you're Vanilla Ice meets Lauryn Hill meets West Side Story." Tell us how you REALLY feel, Brit! Meanwhile, Demi is doing a good job of being the cheerful, supportive equivalent to Paula Abdul, only without the meds (allegedly). We doubt the near perfect harmony between Britney and Demi will carry on all season though!
