Human physical appearance refers to the outward phenotype or look of human beings. There are infinite variations in human phenotypes, though society reduces the variability to distinct categories. Physical appearance of humans, in particular those attributed which are regarded as important for physical attractiveness, are believed by anthropologists to significantly affect the development of personality and social relations. Humans are acutely sensitive to their physical appearance, some theorize for reasons of evolution. Some differences in human appearance are genetic, others are the result of age, lifestyle or disease, and many are the result of personal adornment.

Some people have traditionally linked some differences in personal appearance such as skeletal shape with ethnicity, such as prognathism or elongated stride. Different cultures place different degrees of emphasis on physical appearance and its importance to social status and other phenomena.

Various factors are considered relevant in relation to the physical appearance of humans.

Jones was born and raised in Brooklyn, living much of her adolescent life on the streets after being expelled from home. As a teenager, Kim would rap for fun, being heavily influenced by other female MCs like MC Lyte and Lady of Rage. When word got to The Notorious B.I.G. that she could rhyme, he made Jones perform a freestyle for him on the spot. Impressed with her, he took her in and she began her music career in 1995 with the group Junior M.A.F.I.A., whose debut album Conspiracy generated three hit singles. In late 1996, her solo debut album Hard Core was released. Hard Core was certified double platinum and spawned three consecutive #1 rap hits that included: "No Time" "Not Tonight (Ladies Night remix)" and "Crush on You", a record for a female rapper. Her following albums, The Notorious K.I.M. (2000) and La Bella Mafia (2003), both were certified platinum by the RIAA, making Kim the only female rapper besides Missy Elliott to have at least 3 platinum albums so far. Kim solidified her star power in 2001, when "Lady Marmalade", a song Kim was featured on, went to #1 on the Billboard Hot 100. That made her the second female rapper to earn a #1 on that chart.

Michael Robert "Mike" Posner (born February 12, 1988) is an American singer, songwriter, and producer. Posner released his debut album, 31 Minutes to Takeoff, on August 10, 2010. The album includes the Billboard Hot 100 Top 10 single "Cooler Than Me," his second single, "Please Don't Go," as well as his third single, "Bow Chicka Wow Wow". As of 2012, he is the ambassador of Reebok Classic's RealFlex range.

Posner was born and raised in Southfield, Michigan. His father, a criminal defense attorney, is Jewish, and his mother is Catholic. Posner attended and graduated from Groves High School, where he ran varsity track and cross-country, and went on to attend Duke University. There, Posner went Sigma Nu and graduated in 2010 with a degree in sociology and a certificate in markets and management, with an overall GPA of 3.59.

Manager Daniel Weisman of Elitaste Inc. first heard about Mike Posner in 2008 when Jared Evan manager Saytum passed on some tracks Posner had created for Weisman's then client Wale. Weisman got in touch with Posner and, impressed by songs including "Cooler Than Me", began an informal mentoring relationship with the artist over iChat. The association was made official in early 2009 after Posner's second mixtape, A Matter of Time (the first mixtape being Reflections of a Lost Teen) started attracting industry attention. Working with Don Cannon and DJ Benzi, the mixtape was released from his dorm room at Duke University in March 2009 under the name, "Mike Posner & the Brain Trust," the Brain Trust referring to Posner's supporters. The release was unusual for being distributed for free through iTunes U, a channel designed for educational audio content. Although Posner was not the only artist to take advantage of this loophole, his release was the most organised and high profile, and attracted the largest response, immediately reaching the number one position on the iTunes U chart, thanks to his manager Saytum.
