Amanda Bynes' Latest Feuds

May 29, 2013— -- intro: It seems like every day now, Amanda Bynes has a bone to pick with someone new.

Her latest feud is with former *NSYNC member Lance Bass.

Bass, who worked with Bynes on the 2005 film "Love Wrecked," said during a radio interview on Wednesday that he was "actually really scared" for the troubled starlet. "It's one of those situations where obviously there's some mental problems there and she's not able to see that. We all are," he said. "I hope someone is able to get her the help she needs."

Bynes, who has repeatedly insisted that she is not mentally ill, was not pleased.

"I ignored Lance Bass on twitter and now he is saying I have a mental illness," she tweeted. "Sorry you're an ugly ex boy bander w/ no talent or career."

"I haven't spoken to Lance Bass in 11 years," she continued. "To say I have mental illness out of nowhere makes me lash out! You're making me crazy!"

Bynes, the "Easy A" star, was arrested May 23 after she allegedly threw a bong from her apartment window. She has been charged with tampering with physical evidence, reckless endangerment and criminal possession of marijuana.

Since last summer, after Bynes was charged with a DUI and two counts of hit-and-run, Bynes has launched Twitter attacks on several of her critics. Click through to read a list of her targets.

Bynes then lashed out, calling Teigen an "old ugly model," though both Bynes and Teigen are 27.

"Ur not a pretty model compared to me," Bynes wrote in an extended tweet. "I signed to Ford models @ age 13. I don't look up to u beauty wise. I'm far prettier than u! I'm offended that you're saying I have a mental illness when I show no sign of it, but thankfully not one man that wants me wants you and you are an old ugly model compared to me!

"You look 45!" Bynes added. "You're not pretty so I'm not intimidated by you! I think you're jealous that you're just an ugly model whos career is uninspiring! I don't respect you! You're no beauty queen! I'm a beauty queen!"

The 27-year-old model left it there.

"Nope. Not going to indulge. Wish the best for her, truly," Teigen tweeted, asking her fans not to stoke the flames, either.

They found nothing criminal on me or around me, one cop then sexually assaulted me, so I'm suing for all of the above! I'll be happy when I get money compensation from the cop who assaulted me and NYPD for wrongfully arresting me and having me put into a mental hospital and jail overnight!
