Amanda Bynes waged war on High School Musical 3 actor, Matt Prokop and girlfriend, Sarah Hyland, and, for once, received a taste of her own medicine.

According to Perez Hilton, the Twitter feud started after Bynes tweeted, “If you're not hot I don't care about you.”

Porkop, fed up with Bynes’s “ugly” and hateful Twitter slams, responded to the Amanda Show star, writing, “look in a mirror... Stop getting work done. Save what's left.”

Bynes, not used to getting shot back at, called Prokop’s Modern Family actress girlfriend in typical Bynes fashion, “ugly.”

“@AmandaBynes and my girl is more successful than you ever will be enjoy the long road downhill disgusting crack head,” Propkop fired back, following with, “It's sad @AmandaBynes was a child actress who kids looked up to. Now she's just a lost soul in a plastic face. #gethelp.”

The feud went on from there, with Bynes slammed Prokop for being “ugly” and claiming that she is more of a model than Hyland. “She isn't as pretty as me! You need to put up two comparable professional photos! She's not a model I am!!!” Bynes wrote.

Prokop followed with side by side shot of Hyland and a less-than-desirable photo of Bynes with her new nose job, captioning the photo, “This should clear your mind.”

“You aren't a model you are plastic. Nothing about you is real anymore. It's so sad how blind you are to reality,” Prokop concluded.

Bynes continued to defend herself, saying that getting numerous nose jobs was a necessity for her to have a small nose.

Hyland never jumped in to slam the former Nickelodeon starlet alongside her beau, but instead tweeted that she and Prokop have “officially made it. @AmandaBynes called us ugly! #blessed.”
