Susan Boyle was removed from Heathrow Airport in London on April 25 afternoon after she being incredibly disruptive.
She was then taken by ambulance to the hospital where she was evaluated.
The bizarre story started when London police were called to the British Airways lounge for reports of a distressed woman.
TMZ reports that Susan was taken against her will from the lounge and was taken to an area hospital out of concern for her health. It's believed that she was given a mental health evaluation once there.
The website says the singer, who became a huge star after appearing on "Britain's Got Talent," was "throwing a massive tantrum" when authorities arrived.
Susan's rep told TMZ that she was never on a psychiatric hold.
After her evaluation, Susan was eventually released and got on a different airplane back to Scotland.
In 2013, Susan revealed she has Asperger's Syndrome, which her rep says caused the tantrum.
After her reveal, she told the Daily Mail that she feels at home on stage, but her behavior can get outlandish when she's not in the spotlight. She joked that she is "the only artist who needs a leash! I'm King Kong's mother!"
"Off stage, [my bad behavior] happens lots," she said. "It always has. But I'm getting better at dealing with it because I know what it is. If I feel I'm going to take a mood swing, I get up and leave."
The tantrums, she said, stem from "a sense of panic, not wanting to be there."
"I get depressed," she said. "I just go away, be myself. Then I come back to you. I always come back."
She continued, "It never happens on stage. It seems to make me feel better … When I'm up on stage, even if I've had a bad day, I can become a different person. I feel safe."
On stage with thousands looking up at her, she said, "I don't feel judged up there. I feel accepted."
She said she hoped to use her diagnosis for good.
"I want people to see how it is, to see that you shouldn't judge." She added, "People with Asperger's do put a barrier up because they don't know how to trust people. I try not to. I want to let people in."
