WATCH: Aaron Carter Gets his HIV Test Results

Aaron Carter tested negative for HIV on the September 14th episode of The Doctors — alleviating fears that his plummeting weight was a symptom of the condition. The 29-year-old singer, who is 35 pounds underweight for a man of his height, the doctors said, was the star of a two-part special, hoping to find answers to his many health concerns.

"I need help, I'm scared," he told host Travis Lane Stork. "Because I'm so skinny, I'm still so skinny. And that was the biggest one for me."

Carter was ecstatic to learn  that he was HIV negative.

Carter, whose hits include Aaron's Party and Crazy Little Party Girl, said, "That was the scariest thing I have ever done in my life," he said. "After not getting annual checkups and testing and being safe, actually, being safe so I could be safe for others, more importantly. That's what scared me. I felt like I was putting people at risk with my body. I didn't have the courage to go face the music." Dr. Jorge Rodriguez also tested the former child star for STIs including Chlamydia and syphilis — all negative.

Despite the negative results, Carter was warned by the doctors that he needs to adopt a healthier lifestyle.

"In my opinion, you're not healthy right now, I think your body is hanging on by a thread, seriously," said Rodriguez while Stork added: "You are malnourished, and your body mass index at 17 is in a scary range."

It’s been a crazy few months for the singer. In May his father, Bob Carter, died suddenly and weeks later, he was arrested for driving under the influence in Georgia. In August, Carter came out as bisexual after deciding to free himself of the secret that was "weighing on my chest for nearly half of my life"

Carter said finally opening up about his sexuality "doesn't bring me shame".
