Mariah Carey comes to Foxwoods Resort Casino on Saturday, Oct. 14. The singer-songwriter, known for her five-octave vocal range, will perform in the Grand Theater.

Carey, 47, is one of the most successful recording artists of all time. She has sold more than 220 million records and wrote 17 of her 18 No. 1 singles, including “Always Be My Baby” and “We Belong Together.”

A New Yorker from Huntington, Long Island, Carey began writing poems and songs in high school, where she told people she was going to be a rock star. She waitressed for a brief time before her career took off. It didn’t take long; her debut record became the best-selling album in the country in 1991.

Carey went on to earn multiple Grammy Awards, 21 American Music Awards and Billboard’s “Artist of the Decade” Award, among other honors. Last December, she welcomed viewers into her life via E!’s reality show, “Mariah’s World.” The series followed her as she kicked off an overseas tour.

The star is also known for her philanthropy, involving charities that fight world hunger and AIDS. She supports children’s services in partnership with the Fresh Air Fund; Carey is the Mariah behind Camp Mariah, a retreat for inner city children to explore career development.

She’s also a bit of a diva. Carey has said she can’t help it because it’s in her blood. Earlier this year, in a Paper magazine interview, she said, “I guess it’s a little intense, because I come from a true diva. My mother is an opera singer, and that’s a real diva, you know — Juilliard diva. And so other people that are like, ‘I’m a diva,’ it’s like, ‘Honey, you don’t know what a diva is, you didn’t grow up with my mom.’ ”

In addition, Carey is known for her film work, appearing in “Precious” (2009) and Lee Daniel’s “The Butler” (2013). She made her directorial debut in “A Christmas Melody,” a 2015 feature for Hallmark, in which she also starred.
