Los Angeles (CNN) -- Paris Jackson, the 15-year-old daughter of Michael Jackson, was rushed to a hospital early Wednesday morning, sources close to the Jackson family told CNN.
Katherine Jackson's personal lawyer told CNN that Paris "is OK."
"Being a sensitive 15-year-old is difficult no matter who you are," attorney Perry Sanders said Wednesday morning. "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."
Other Jackson sources stopped short of calling the incident a suicide attempt, although one suggested it might be "a cry for help" from the teenager.
Paris posted messages to her million-plus Twitter followers late Tuesday evening:
"I wonder why tears are salty?"
"Yesterday, all my troubles seemed so far away.”
"Now it looks as though they're here to stay."
The Los Angeles County Sheriff's Department said its deputies "responded to a medical situation" at an address that matches the Jackson's Calabasas home at 1:27 a.m. Wednesday. A patient was taken to a hospital, it said.
Paris was recently reunited with her mother, who bowed out of her life when she was an infant. She has been spending time with Debbie Rowe on her horse farm.
Rowe issued a statement through her lawyer Wednesday morning: "We appreciate everyone's thoughts for Paris at this time and their respect for the family's privacy."
Paris, along with her grandmother, Katherine Jackson, and her brothers, Prince and Blanket, are suing AEG Live for liability in Michael Jackson's 2009 drug overdose death.
Paris and Prince are scheduled to testify in the wrongful death trial later this month. Both teens were questioned in depositions for two days each by AEG lawyers in recent months.
Paris made millions cry four years ago when she spoke up at the end of the public memorial service for her father.
"Ever since I was born, daddy has been the best father you could ever imagine," she said, fighting back tears as relatives consoled her. "And I just want to say that I love him so much," she said as she burst into tears and sought refuge in the embrace of family members.
