The Jackson family would not confirm the attempted suicide, but issued a statement through its attorney: "Being a sensitive 15 year old is difficult no matter who you are. It is especially difficult when you lose the person closest to you. Paris is physically fine and is getting appropriate medical attention. Please respect her privacy and the family's privacy."
Paris and Prince Michael are the children of Michael Jackson's 54-year-old ex-wife Debbie Rowe. People Magazine reports that Paris had been spending time with Rowe recently.
A 20-minute video of the teen applying makeup was posted to YouTube last week. Paris says on Twitter she doesn't know how the video, in which she repeatedly asserts, "I am so weird," ended up on the site.
"I hope you guys liked it tho and didn't think i'm too crazy," she wrote. "i get weird when i'm not around people lol."
Early Wednesday morning, Paris Tweeted a line from The Beatles' hit song, "Yesterday."
"Yesterday, all my troubles seemed so far away now it looks as though they're here to stay," she wrote.
TMZ quoted a source close to her saying Paris has tried to commit suicide in the past, but this was "far more serious."
Michael Jackson died in 2009 at the age of 50 from an overdose of the anesthetic propofol.
Katherine Jackson shares guardianship of her son's three children - Paris and her brothers Prince, 16, and Blanket, 11 - with the singer's nephew, TJ Jackson.
Michael Jackson kept his children out of the spotlight during his lifetime. After his death, the children took on a more public life, appearing at memorials and commemorations of their father.
The children are listed as plaintiffs in a lawsuit filed by their grandmother against concert giant AEG Live LLC, who she claims is responsible for her son's death. Katherine Jackson's lawsuit claims AEG failed to properly investigate the doctor convicted of causing the singer's death, and pushed the superstar to rehearse and perform a planned series of 50 comeback shows titled "This Is It."
Paris and Prince are listed as potential witnesses in the case, which is in its sixth week of trial.
Katherine Jackson's trial attorney, Brian Panish, declined comment Wednesday morning on Paris Jackson's condition. Her hospitalization came hours after AEG Live's CEO Randy Phillips told a jury that he believed the lawsuit was a shakedown and extortion attempt and that the company should not be held responsible for Michael Jackson's death.
