Amanda Bynes is at it again, calling yet another celebrity “ugly,” and this time it’s former High School Musical star Zac Efron.

She has called everyone from model Chrissy Teigen, to Rihanna, to Drake “ugly” and now it’s apparently Efron’s turn. After tweeting "@zacefron has an ugly face,” she soon deleted it.

Bynes also yet again threatened to sue over a picture she didn’t like, tweeting “OH MY GOD! THAT'S NOT ME! They morphed my face onto someone with a different face shape! I'm suing any site/magazine that shares that image!”

More recently, she told her over 2 million followers that she loves getting surgery, already having two nose jobs done.

She followed up with, “I Plan On Having Surgery On My Whole Face Straight Up.”

Actor Seth Rogen recently joked about Bynes, saying he’s “avoided her wrath so far.” He also told Mashable of her constant presence on Twitter, "I think it's a difficult temptation. If you're the type of person that has poor decision-making abilities then having instant access to thousands, if not millions and millions of people, is maybe not the best thing for you.”

He added, "A lot of these people are really proving that. When it used to be harder to expose your insanity to the world, it was probably more beneficial for, you know, people who were crazier. Now, with 140 characters, you can really change your perception of people instantaneously, or people's perception of you. I've typed and deleted several tweets that could have been potentially threatening.”
