Feud Between Donald Trump and Rosie O'Donnell Gets Heated

The ongoing feud between Donald Trump and Rosie O’Donnell heats up again as the two engage in a mud-slinging war of words on Twitter. INSIDE EDITION caught with Trump to get his reaction.

Brace yourself for "Doctor Donald." Now he's actually dispensing psychological advice to his arch-enemy, Rosie O'Donnell.

Trump told INSIDE EDITION's Paul Boyd, "Rosie is a major loser. Rosie should really see a psychiatrist. She tweets constantly. She needs attention because nobody's watching her show."

It's the latest bombshell in the ongoing O'Donnell-Trump feud. And if you think that was just a flippant remark, Trump also fired off these tweets for all the world to see:

Trump fired off this stunning tweet for all the world to see:

"Please send a psychiatrist to help Rosie, she's in a bad state."

Boyd asked, "Is it getting too personal Mr. Trump?"

"No, it's not personal," said Trump.

O'Donnell is actually gloating about the ongoing feud on her Twitter page, tweeting: "I had a twitter fight with The Donald this a.m. - fun fun fun."

O'Donnell's good friend Joy Behar warned comedian Dennis Leary about the wrath of Trump, saying, "If you say anything about him, he goes after you!"

But Leary couldn't resist poking fun of his hairdo, the way O'Donnell does.

"Most guys, they do a combover from [the side] but I think he's swirling it around like cotton candy," said Leary.

Trump's response to that barb?

"Who's Dennis Leary?" asked Trump.

Ouch! The Trump-O'Donnell feud was put in perfect perspective by Aiesha Taylor of The Talk.

"Trump and Rosie are turning into the Hatfields and the McCoys," said Taylor.

Trump is busy hustling his latest book, Time to Get Tough, holding a book signing in the lobby at Trump Tower in Manhattan, and he intends to stay tough in his feud with O'Donnell.

INSIDE EDITION's Paul Boyd asked Trump, "In the spirit of Christmas, any chance of a truce between you and Rosie O'Donnell?"

"No. No chance," said Trump.
