The 'Easy A' actress reportedly hates the comparison because she believes she's better than Lohan, who is upset that Bynes hasn't been punished despite her repeated traffic violations, Chicago Sun-Times reported.
"Amanda is furious about being compared to Lindsay, who has had a long history of substance abuse and so many problems. Amanda has that one DUI and that's not good, but you can't really compare the two of them," a source told the newspaper.
Lohan was upset that Bynes was let off easily for the same crime which landed her in jail.
"Why did I get put in jail and a nickelodeon star has had NO punishment(s) so far?" Lohan tweeted.
Bynes is currently facing a DUI charge and two counts of hit-and-run misdemeanor. Her driving mishaps led to her license being suspended and her car being impounded when she ignored judge's order not to drive without a valid license.
