Gone are the days of shouting at each other face-to-face, because now it's all about trading insults in 140 characters or less.
Over the weekend, X Factor star Tulisa hit out at Lord Alan Sugar after he tweeted comments about her validation on the X Factor. Not one to take things lying down, the star took to the social networking site to brand him a "t**t".
However, this isn't the first time reality TV stars have traded insults with each other on Twitter. Who can forget the humdinger of an argument between The Only Way Is Essex's Mario Falcone and The Wanted's Tom Parker.
Defending Lydia Bright and her mum after Tom posted a comment about their "famous" status, Mario hit out at the popstar tweeted back: "Is he the ugly one in the band? Working? u mean recording songs others have written?
"The only one everyone has heard of us max... He just makes up the numbers the tool."
It's fair to say the argument went on for quite a while. However, they weren't the only one's hitting out at each other. Sharing her views after Kourtney Kardashian announced she was pregnant again, Teen Mom's Farah Abraham tweeted: "Im Shocked Kourtney Kardashian is pregnant again, Did she not learn anything from TEEN MOM? Maybe its a fake pregnancy like kims wedding SAD."
Responding to Farah's tweet, Kourtney replied: "Why would I have anything to do with teen mom? I'm 32 years old! I may look young honey, but don't get it twisted. :)"
Even movie star Lindsay Lohan had a pop at Dr Phil, tweeting: "I thought REAL doctors talk to patients in offices behind closed doors. Am I wrong? Hmmmmm. I think NOT! Yay!"
Having failed to check the authenticity of a still of Snooki with subtitles claiming her saying that she won't be changing her son's diapers, Teen Mom's Jenelle Evans who accused her of being "f***ed up." Responding to her claims, Snooki tweeted:
"FYI, I can't wait to change my kid's sh***y diapers & I don't even believe in maids. Just saying."
What do you think?
It's just not TV stars who are at it! Music star's biggest Twitter feuds
CHRIS BROWN VERSUS RAZ B: Chris Brown is now stranger to Twitter fueds (this won't be his only appearance on the list) but possibly most heated feud was with former B2K singer Raz B.

Grow up!!! Di*** in da booty ass lil boy," and only getting worse from there.
