Twilight Stars -- Mama Gonna Knock You Out

Hell hath no fury like a "Twi-hard" scorned ... fortunately, Kellan Lutz is one talented unscorner.

Amidst the chaos at last night's big Westwood premiere of "New Moon," one extremely passionate mama went off on some of the stars when they wouldn't stop to sign autographs.

But while her daughter wretched with embarrassment, mama's tactics eventually worked -- she somehow got Kellan's attention and the dude actually stopped to take some pics with her extremely lucky daughter!

Forget about the Wolf Pack or the Volturi -- the TwilightMOMS are the ones to watch out for.
