There's no love lost between Cher and Donald Trump.
The stars exchanged bitter words over Twitter and beyond this week, with the singer signing the petition urging Macy's to fire Trump and the mogul responding in kind.
Upon discovering the petition to get the store to cut ties with Trump's brands, Cher announced she intended to sign it and boycott the store until it dumps the Donald.
"I'll NEVER GO TO MACY'S AGAIN!" Cher Tweeted.
"I didnt know they sold Donald Trump's Line! They don't care that they sell products from a LOUDMOUTH 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!"
The petition takes issue with Trump for his "racially charged birther conspiracy" theory against President Obama, "sexist behavior," and for being a climate change denier.
And general obnoxiousness and the bad combover. Just kidding.
Cher's message prompted Trump to respond, going on Fox News and proclaiming, "Cher is somewhat of a loser. She's lonely, she's unhappy, she's very miserable."
He also Tweeted at her directly: “@cher - I don’t wear a “rug” - it’s mine. And I promise not to talk about your massive plastic surgeries that didn't work.”
“It’s amazing how people can talk about me but I’m not allowed to talk about them.”
The feud seems to have rekindled the bad blood between two, which started in May as Cher dissed presidential candidate Mitt Romney, Trump and the conservative right.
"If ROMNEY gets elected I don't know if I can breathe same air as Him & his Right Wing Racist Homophobic Women Hating Tea Bagger Masters," Cher wrote.
And that about brings you up to date ... until The Donald's next Tweet.
