Mariah Carey (born March 27, 1969 or 1970) is an American singer, songwriter, actress, and record producer. Referred to as the "Songbird Supreme" by Guinness World Records, she is noted for her five-octave vocal range, melismatic singing style, and signature use of the whistle register.

She rose to fame in 1990 after signing to Columbia Records and releasing her eponymous debut album, which topped the U.S. Billboard 200 for eleven consecutive weeks. Soon after, Carey became the only artist ever to have their first five singles reach number one on the U.S. Billboard Hot 100 chart, from "Vision of Love" to "Emotions".

Donald John Trump (born June 14, 1946) is the 45th and current president of the United States. Before entering politics, he was a businessman and television personality. Trump was born and raised in the New York City borough of Queens, and received a bachelor's degree in economics from the Wharton School. He took charge of his family's real-estate business in 1971, renamed it The Trump Organization, and expanded its operations from Queens and Brooklyn into Manhattan.

The company built or renovated skyscrapers, hotels, casinos, and golf courses. Trump later started various side ventures, mostly by licensing his name. He owned the Miss Universe and Miss USA beauty pageants from 1996 to 2015, and produced and hosted The Apprentice, a reality television show, from 2003 to 2015. Forbes estimates his net worth to be $3.1 billion.
