Donald Trump is never one to stay quiet, much less on Twitter. The real estate tycoon and Daily Show host Jon Stewart who have been battling each other via the popular social media site, attacking each other for everything from politics to their persona, engaged in a brand new feud on Friday.

"He's an overrated a--hole," Trump told a follower of Stewart. "Total phony."

Last week, Trump hit at Stewart on Twitter, calling him with his birth name. "I promise you that I'm much smarter than Jonathan Leibowitz - I mean Jon Stewart @TheDailyShow," Trump tweeted, adding, "who, by the way, is totally overrated."

But on Wednesday, Stewart came back at Trump and invoked Trump's comments saying "By the way, did you know Donald Trump's birth name is F**kface Von Clownstick?" (WATCH BELOW)

Trump, however was quick to respond to the feud, further questioning Stewart's integrity slamming him for being disrespectful to his culture. "What's funny about the name "F**kface Von Clownstick" - it was not coined by Jon Leibowitz - he stole it from some moron on twitter. If Jon Stewart is so above it all & legit, why did he change his name from Jonathan Leibowitz?" tweeted Trump. "He should be proud of his heritage! Jon Stewart @TheDailyShow is a total phony - he should cherish his past - not run from it."

Stewart however replied with a joke as usual: "Can't an overrated Jew have a complicated relationship with his dad without being accused of hiding his heritage? #FuckFaceVonClownstick."
