Aaron Carter and fiancée Melanie Martin have broken up.

Less than a week after their son's birth, the "I Want Candy" singer took to Twitter early Tuesday morning to reveal that they "decided to go our separate ways."

"There has been a very big lie and my sister communicating w my ex fiancé ruined everything considering she knew what angel tried to do to me in court thanks angel you ruined my family," he continued, referencing his estranged twin sister, Angel Conrad, who has a restraining order against Carter, per TMZ.

In an interview with the outlet, Carter explained that he felt betrayed after friends told him about Martin regularly communicating with Conrad. He also claimed that Martin would talk to members of Carter's family each time the pair broke up, which he believed was part of their plan to place him in a conservatorship.

"I can't even shed a tear. I'm in utter shock," Carter said in another tweet. "I don't have a family now. I was deceived and lied too [sic]. I can't believe she betrayed [me] this way. I gave her the world. There's more to the story then [sic] meets the eye. My Heart hurts broken heart."

He then went on call Martin's actions "unforgivable" and said "she knew what my twin sister and my brother were doing to me right before I met her." Carter also claimed she knew he didn't want her speaking to his family and lied about talking to them after he "asked her many times" about it.

According to a subsequent post, he also revealed Martin was moving to Las Vegas and accused her of having a "back up plan this whole time," before saying she said he'll "never see" their son, Prince, again.

"I’ve never felt more devastated and betrayed and lied to in my entire life this is such a horrible situation considering prince doesn’t deserve any of this," Carter continued. "And now it’s my job to just be a single father and that’s what’s gonna happen."

However, Carter returned to Twitter several hours later to say "Mel and I appreciate the support and concern we have been shown" and reassuring fans that they would "continue to make prince our priority during this difficult time."

As for Martin, she told TMZ that she doesn't think Carter's family want him in a conservatorship. Additionally, sources told the tabloid that Nick Carter has not spoken to Martin and is not trying to place his younger brother under some sort of legal guardianship.
