Ladies and gentlemen, here you have it: The ugliest Twitter war of 2012!

An online petition released last Monday to discontinue Donald Trump's clothing line at Macy's because of his controversial Birther views and allegedly racist remarks about Barack Obama has received over 500,000 signatures so far. It also appears that Cher is part of that growing group. "I'll NEVER GO TO MACY'S AGAIN! I didn't know they sold Donald Trump's Line! If they don't care that they sell products from a LOUDMOUTH," she tweeted. "RACIST CRETIN, WHO'D LIE LIKE 'HIS RUG' TO GET SOME CHEAP PRESS! I CANT BELIEVE MACY'S THINKS HE'S THE RIGHT 'MAN' 2 REPRESENT THEIR NAME!" Okay, Cher. Based on the all-caps, we get it. You're angry.

Never one to turn a good publicity opportunity, The Donald got equally nasty with his remarks in response to Cher. "@cher should spend more time focusing on her family and dying career!" he immediately tweeted back. I don't wear a 'rug'—it's mine. And I promise not to talk about your massive plastic surgeries that didn't work." Ouch!

Safe to say that Cher and Chaz Bono won't be invited on Celebrity Apprentice anytime soon!
