Nick Carter files restraining order against Aaron Carter due to his 'alarming behavior' and alleged murder threat

It's been a wild past day for the Carter family after Backstreet Boys singer Nick Carter publicly accused his brother, Aaron Carter, of threatening murder.

Backstreet Boys singer Nick Carter announced Tuesday he is filing a restraining order against his brother, citing his "increasingly alarming behavior." This includes an alleged threat, with Nick Carter claiming his brother confessed to harboring "thoughts and intentions of killing my pregnant wife and unborn child."

Aaron Carter, who recently opened up about being diagnosed with multiple personality disorder and schizophrenia, denied his brother's claim, tweeting, "I do not wish harm to anyone, especially my family" and writing that he "never threatened anyone."

He has gone on to rail against his brother in many tweets over the course of several hours, bringing up previous allegations of rape made against Nick Carter. Melissa Schuman in 2017 accused Nick Carter of raping her more than 15 years earlier, but he was not charged due to the statute of limitations having expired, CNN reports. Nick Carter denied the allegations.

"#CoverUp," Aaron Carter wrote in several tweets, in one publicly asking for help from actress and activist Rose McGowan and suggesting journalist Aphrodite Jones make an "r Kelly type documentary."
