The New York Post claims that the cast of the controversial show were each paid just a few hundred dollars for each episode in the first season.
The group is now allegedly demanding $10,000 (£6,200) per episode if the programme is renewed.
An insider explained: "They want $10,000 an episode, arguing that the stars from The Hills get $100,000 (£62,000) and that show doesn't even rate as high.
"They're hanging together like the cast of Friends and saying if they don't all get the pay increase, none of them will return."
A representative for MTV would not comment on the negotiations but said: "We have not yet confirmed a season two."
