KIM G had a surprise for her rival Danielle Staub‘s 48th birthday — she crashed Staub’s party at Scores. The pint-size lackey on “The Real Housewives of New Jersey” hopped onto the red carpet outside the mammary mecca shouting that she wasn’t invited and didn’t care. Staub waited angrily, telling organizers she wouldn’t leave her car until Kim G left. Kim G walked off and hid in a tinted Honda CRV feet away from the press gaggle as Staub made her way saying, “Kim G who?” Staub tripped four times while performing onstage with her lesbian lover Lori Michaels. A former stripper, Staub told us, “Scores is a comfort zone for me.”
