The Donald Trump-Martha Stewart feud seems to be back on, with Stewart blasting Trump for firing his former Apprentice sidekick Carolyn Kepcher.

"Donald is out of control," Stewart tells TV's Access Hollywood. "By the time he's finished, he will have fired everyone around him and there will be nobody left."

She continues, "Poor Donald will be sitting there on his little pedestal all by himself. He needs to be careful!"

In his own statement on Friday, Trump shot back: "Martha will always be upset with me because her version of The Apprentice was a complete failure and my version remains a tremendous success. Despite that, I still love Martha"

The two moguls first butted heads in October 2005, when Trump blamed Stewart, whose Apprentice spin-off had premiered a month earlier, for pulling viewers away from his own version.

Firing back, Stewart told Fortune she'd expected to fire Trump and that her show would replace his. Stewart's Apprentice was cancelled in November.

The feud came to a head in February, when Trump skewered Stewart in an open letter blaming her performance for her show's failure and writing in a P.S., "Be careful or I will do a syndicated daytime show, perhaps called The Boardroom, and further destroy the meager ratings you already have!"

"I almost can't believe my longtime friend Donald Trump wrote it," Stewart said in a statement to PEOPLE at the time.
