Last month, the two took turns exchanging embarrassing photos of each other on Twitter after Amanda expressed her anger that media outlets were using paparazzi pics instead of the ones she posted on Twitter.
Now, the duo is back in the ring for round two, but this time, they're having a war of words...and to quote Amanda's go-to insult, it's getting "ugly."
After Perez tweeted an article that contained a photo of Amanda jumping on a trampoline in New York City, Amanda fired off the following:
"THAT'S NOT ME! I'm so sick of fake fans such as Perez Hilton! Send the picture to me privately first to confirm that it's me! I've never been to SkyZone! That looks nothing like me! I don't own a brown wig!"
(In unrelated news, Amanda was spotted out and about in New York this week wearing her brown wig.)
Amanda wasn't done yet, though. She then posted another tweet telling Perez to "stop living...kill yourself" along with another string of insults that we'd have to censor so hard, you wouldn't be able to make sense of it. (You can read it here)
As you can imagine, Perez didn't appreciate Amanda's unsolicited opinion all that much. "D*mn, girl. You go hard!" he wrote. "Unfortunately, the way you're heading you will likely end up dead before I kill myself. #Truth"
He then told Amanda that he hoped she didn't join the "27 club" and quoted Courtney Love's advice to her, saying that she needs to "get it together."
Having an argument is one thing, but do you think Amanda crossed the line when she told Perez to kill himself?
