Aaron Carter, the brother of Backstreet Boys star Nick Carter, has died.
The 34-year-old singer was found at his home in California after police officers received a 911 call at 11am on Saturday.
His representatives confirmed his death earlier this evening.
A spokesperson for the Los Angeles Police Department said that a suspicious death took place at Carter's property - but could not confirm the identity.
"Right now it's a really bad time we're trying to figure out what happened and what the cause of it was," a representative from the singer's team told the PA news agency.
"We're just as upset as everyone and hope that fans can give thoughts and prayers to his family."
Aaron, the brother of Backstreet Boy's Nick Carter, was launched into the spotlight after he opened for them on their 1997 tour.
He also supported Britney Spears when he was younger, and he got his first record deal when he was just nine.
Aaron later released his self-titled album Aaron Carter, which reached gold status.
He went on to release Aaron's Party (Come and Get It) in 2000, which went triple platinum.
His brother Nick has not confirmed anything on Instagram.
The last post he shared was on stage with the boys in Germany.
Aaron was pulled over this week after his former girlfriend Melanie Martin "called the police" on him.
TMZ reported that cops got a call about a driver possibly driving whilst under the influence and swerving through traffic.
Aaron was tested for alcohol in his system at the time, and the results revealed that he had not been drinking.
Melanie, 35, who shares a son with Aaron, was driving behind him at the time of the call.
After the investigation was completed, Aaron accidentally locked his keys inside the vehicle and had to retrieve them by climbing through the roof hatch.
He is survived by his twin sister, Angel and sister Bobbie Jean.
Aaron's sister Leslie passed away in 2012 when she was 25 from a drug overdose
The singer had a half sister Virginia Marie, half brother Kaden and stepsister Taelyn.
Aaron's last Instagram post was of his latest song that he collaborated on with Mic Garcia.
In Garcia's latest Instagram story he is seen looking at his phone with a shocked expression.
"That's not real bro, that's not real," he repeated.
He continued: "That's not real, I was coming there tomorrow, that's not real. Oh my god please, this is not a f****** joke. What the f*** is going on?"
Aaron became a father in November last year.
However, he and Melanie split just two days after they welcomed their son Prince.
He has spoken openly about his battles with substance abuse and his mental health.
He appeared on the show The Doctors, where he spoke about the pills he was taking.
In a social media live a few months ago, he said that he hadn't relapsed but was checking into a rehab to help him cope.
He said, "I haven't had any relapses or anything like that, it's just triggers are big right now for me [and] I want my son back,"
"The main reason why I enrolled into Lionrock Recovery outpatient is to help with the weed."
After one of his and Melanie's break ups, he posted on his Instagram story: "I'm literally trapped inside my own bedroom because my ex will not leave my house ."
The Mirror has approached his representative for comment.
