Idina Kim Menzel ( /ɪˈdiːnə mɛnˈzɛl/; born Mentzel on May 30, 1971) is an American actress, singer and songwriter.

She rose to prominence for her performance as Maureen Johnson in the Broadway musical Rent, a role which she reprised for the 2005 film adaptation. In 2004 she won the Tony Award for originating the role of Elphaba in the hugely successful Broadway blockbuster Wicked.

Menzel was born in Queens, New York. Her mother, Helene, is a therapist, and her father, Stuart Mentzel, worked as a pajama salesman. Her family is Jewish; her grandparents immigrated from Russia and elsewhere in Eastern Europe. Her family lived in East Brunswick, Somerset and Marlboro, New Jersey from when she was in kindergarten to third grade, but she considers herself raised in Syosset, New York, with her younger sister Cara. Idina changed her last name to Menzel to better reflect the pronunciation the Mentzel family had adopted in America. When Menzel was 15 years old, her parents divorced and she began working as a wedding and bar mitzvah singer, a job which she continued throughout her time at New York University's Tisch School of the Arts. She earned a Bachelors of Fine Arts degree in Drama at NYU prior to being cast in Jonathan Larson's rock musical Rent. She was friends with actor Adam Pascal before they worked together in Rent.

Michael Joseph Jackson (August 29, 1958 – June 25, 2009) was an American recording artist, entertainer, and businessman. Often referred to as the King of Pop, or by his initials MJ, Jackson is recognized as the most successful entertainer of all time by Guinness World Records. His contribution to music, dance, and fashion, along with a much-publicized personal life, made him a global figure in popular culture for over four decades. The seventh child of the Jackson family, he debuted on the professional music scene along with his brothers as a member of The Jackson 5 in 1964, and began his solo career in 1971.

In the early 1980s, Jackson became a dominant figure in popular music. The music videos for his songs, including those of "Beat It", "Billie Jean", and "Thriller", were credited with transforming the medium into an art form and a promotional tool, and the popularity of these videos helped to bring the relatively new television channel MTV to fame. Videos such as "Black or White" and "Scream" made him a staple on MTV in the 1990s. Through stage performances and music videos, Jackson popularized a number of complicated dance techniques, such as the robot and the moonwalk, to which he gave the name. His distinctive musical sound and vocal style influenced numerous hip hop, post-disco, contemporary R&B, pop and rock artists.
