There is something wrong with Amanda Bynes, says Lance Bass. The actress and the Dirty Pop with Lance Bass host were once thick as thieves. But recently, Bass has felt the wrath of Amanda’s twitter stream, like so many stars before him. Bynes’ outburst was prompted by Bass suggesting that the 27-year-old Nickelodeon star might be suffering from a mental disorder.

"She deleted all of her email addresses and cell phone numbers so none of her friends can get in touch with her," Bass said on his SiriusXM show, according to New York Daily News. Bass claims that his former pal has cut off all communication with family and friends and the only way to get any insight into her life is through her twitter stream: "Everything is deleted. She obviously has a cell," he continued. "She's tweeting, but none of her friends can get to her. Her family and friends can't get to her ... so the only way into her life is through Twitter."

Meanwhile, Amanda hasn’t been keeping quiet about Lance either. She claims that his mental disorder comment wasn’t prompted by concern, it was just Bass trying to get her attention... or something of that sort, it isn’t quite clear: "I ignored Lance Bass on twitter and now he is saying I have a mental illness," Bynes tweeted. "Sorry you're an ugly ex boy band member w/no talent or career."

Ouch. Apply cold water to burn area, Lance. In a separate tweet, Bynes continued: "I haven't spoken to Lance Bass in 11 years. To say I have a mental illness out of nowhere makes me lash out! You're making me crazy!"

That doesn’t seem to be completely accurate though, as pictures exist of the two hanging out as recently as 2011, which means that the eccentric starlet is getting her dates seriously mixed up. Meanwhile, with or without intervention from Lance Bass, Amanda’s erratic behavior continues. Her most recent stint reportedly included shelling out $1000 for three Disney princess-inspired wigs.
