If you take on one Kardashian, you take on the whole family. After middle sister Kim took a flour bomb to the back at the launch of her new perfume on Thursday night, Kourtney and Khloe went straight to the Twitterverse to give their sister’s salty (or, um, flour-y) hater a piece of their minds.

“Classy to flour bomb my sister at her charity event helping women,” Kourtney tweeted. “I wonder if they would have dared thrown the flour at my hormonal and pregnant self!”

Khloe also chimed in, though with a little more radical comment. “I wish I was with my sister tonight, she wrote. “I bet you that woman wouldn't have dared tried [sic] a thing...” Them’s fightin’ words, Khloe! But in all seriousness, she is the Kardashian we’d least want to mess with. We’ve all seen the way she tackles Henry the Giraffe!

As for momager Kris Jenner, she focused on her daughter’s calm reaction rather than criticizing the attacker herself. On her Celebuzz blog, she wrote, "I am so proud of my daughter for handling this situation so professionally and with such poise! Kim wasn't phased by the attack and simply walked away from the red carpet, brushed herself off and headed right back out!!"

Although a few snarky fans responded negatively to Kourtney and Khloe’s tweet with sentiments like “What would you do?,” they all seemed to agree that Kim handled the situation with amazing grace. ‘Atta girl!
