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.
