Cher and Donald Trump were feuding on Twitter.

Donald Trump has been making his opinions known on Twitter for some time now, earning special attention for posts he made after President Barack Obama was re-elected on Nov. 6.

But now another big celebrity has jumped into the arena and is engaging in a Twitter fight with the billionaire -- Cher.

Cher's not the only one who objects to Macy's involvement with Trump. Over a half-million people have signed a petition asking the department store chain to cut ties with the billionaire, saying otherwise they will cut up their Macy's credit cards.

Stay tuned. With two such vocal and Twitter-happy celebs involved, this feud may not be over.
