Singer. Born March 27, 1970, in Long Island, New York to Alfred Roy Carey, a Venezuelan aeronautical engineer; and Patricia Carey, a voice coach and opera singer. Has two older siblings: a brother, Morgan, and a sister, Alison.
Carey is known as one of the top “pop divas” of the 1990s, having sold more than eighty million albums worldwide. Her voice spans more than five octaves and she writes most of her own music.

Carey’s parents divorced when she was three. She stunned her mother by imitating her operatic singing as early as age two, and was given singing lessons starting at age four. After graduating in 1987 from Harborfields High School in Greenlawn, New York, Carey moved to Manhattan where she worked as a waitress, coat check girl, and studied cosmetology while writing songs and actively pursuing a music career at night.

When she was eighteen, Carey and her friend, singer Brenda K. Starr, went to a party hosted by CBS Records. Starr convinced Carey to bring along one of her demo tapes. She intended to give the tape to Columbia’s Jerry Greenberg, but Tommy Mottola, the president of Columbia Records (later Sony), intercepted it before she could hand it to Greenberg. After listening to the tape on the way home from the party, Mottola signed Carey immediately and set her to work on her first album, Mariah Carey (1990) which included four No. 1 singles: “Vision of Love,” “Love Takes Time,” “Some Day,” and “I Don’t Wanna Cry.” Her second album Emotions was released in 1992; the title track became her fifth No. 1 single, and included hits “Can’t Let Go” and “Make it happen. This performance was released as an album and a home video, resulting in another No. 1 single (a cover of The Jacksons’ “I’ll Be There”). Her next album Music Box (1993) cut back a bit on the lavish studio production techniques heard in her previous albums, and included the No. 1 singles, “Dreamlover” and “Hero.” Her November 1994 release Merry Christmas combined traditional Christian hymns with new songs. In 1995 she released Daydream; the first single “Fantasy” debuted at No. 1. It also included collaborations with R&B and hip-hop artists, such as Wu-Tang Clan and Boyz II Men (“One Sweet Day”).
 In July 2001, Carey was admitted into a New York-area hospital and put under psychiatric care after suffering what her publicists called a "physical and emotional collapse." Carey had been preparing to promote her upcoming feature film debut, Glitter, and its accompanying soundtrack album, but cancelled all public appearances. The release of Glitter was subsequently pushed back from late August to late September 2001. Carey was released from the hospital after two weeks.In January 2002, Carey and EMI (the corporate owner of Virgin Records, with whom Carey had signed a reported $80 million contract in April 2001) severed their relationship. Though the film and soundtrack for Glitter failed to generate the desired box office and sales totals, Carey reportedly walked away from Virgin with nearly $50 million as part of her severance agreement. In May of 2002, she signed a deal with Universal Music Group's Island/Def Jam Records. In December 2002, Carey staged a comeback with her eighth album, Charmbracelet, which debuted in third place on the charts. The record's accompanying tour, her first in more than three years, launched in June 2003.
