The human back is the large posterior area of the human body, rising from the top of the buttocks to the back of the neck and the shoulders. It is the surface opposite to the chest, its height being defined by the vertebral column (commonly referred to as the spine or backbone) and its breadth being supported by the ribcage and shoulders. The spinal canal runs through the spine and provides nerves to the rest of the body.

The central feature of the human back is the vertebral column, specifically the length from the top of the thoracic vertebrae to the bottom of the lumbar vertebrae, which houses the spinal cord in its spinal canal, and which generally has some curvature that gives shape to the back. The ribcage extends from the spine at the top of the back (with the top of the ribcage corresponding to the T1 vertebra), more than halfway down the length of the back, leaving an area with less protection between the bottom of the ribcage and the hips. The width of the back at the top is defined by the scapula, the broad, flat bones of the shoulders.

Cher Lloyd (born 28 July 1993) is an English recording artist. Lloyd rose to fame when she finished fourth in the seventh series of The X Factor. Shortly afterwards, Lloyd was signed by Simon Cowell to Sony Music subsidiary Syco Music.

Cher Lloyd's debut single "Swagger Jagger" was released in June 2011. Despite receiving negative reviews, the single entered at number one on the UK Singles Chart and number two on the Irish Singles Chart. Her second single "With Ur Love" was released on 31 October, featuring Mike Posner, and peaked at number four in the UK, and number five in Ireland, preceding her debut album Sticks + Stones, which peaked at number four in the UK Albums Chart and number seven on the Irish Albums Chart.

Cher Lloyd used to live in Malvern with her parents Darren and Dina, and three younger siblings brother Josh, and sisters Sophie and Rosie. Lloyd attended Dyson Perrins CE Sports College, where she studied performing arts. She also attended theatre arts school Stagecoach.

Lloyd had previously auditioned for The X Factor twice before (when the minimum age was lower) singing ballads, but did not make it through. Lloyd has previously performed at holiday camps and said she gets a mixed reaction to her music, but was a big hit with x-factor judge at the time Cheryl Cole. She remarked on their similarity and Cheryl went on to support her throughout the show. She auditioned singing the Keri Hilson version of "Turn My Swag On". At bootcamp she sang a rap version of "Viva La Vida" adding lyrics she claimed to have written herself, but this was disputed and reports claimed she took them from a song by rapper Swizz Beatz. At the judges' houses she performed "Cooler Than Me" but suffered from tonsillitis and was unable to complete her song. She was given a second chance, but broke down sobbing and could not complete the song. Despite this, she was still picked as one of the final three girls by mentor Cheryl Cole.

Taylor Alison Swift (born December 13, 1989) is an American singer-songwriter and occasional actress. Raised in Wyomissing, Pennsylvania, Swift moved to Nashville, Tennessee at the age of fourteen to pursue a career in country music. She signed to the independent label Big Machine Records and became the youngest songwriter ever hired by the Sony/ATV Music publishing house. The release of Swift's self-titled debut album in 2006 established her as a country music star. "Our Song", her third single, made her the youngest sole writer and singer of a number one song on the country chart. She received a Best New Artist nomination at the 50th Grammy Awards.

Swift's second album, Fearless, was released in late 2008. Buoyed by the chart success of the singles "Love Story" and "You Belong with Me", Fearless attracted a crossover audience and became the top-selling album of 2009. The record won four Grammy Awards, with Swift becoming the youngest ever Album of the Year winner. Fearless also received Album of the Year plaudits at the American Music Awards, Academy of Country Music Awards and Country Music Association Awards, making it the most awarded album in country music history. In 2010, Swift released her third album, Speak Now, which sold over one million copies in its first week. She then embarked on the 111-date Speak Now World Tour, which was attended by over 1.6 million fans and has become one of the highest-grossing concert tours of all time. The album's third single, "Mean", won two Grammy Awards for Best Country Song and Best Country Solo Performance. Swift is currently recording her fourth studio album, due for release in the fall of 2012.

Kobe Bean Bryant (born August 23, 1978) is an American professional basketball player who plays shooting guard for the Los Angeles Lakers of the National Basketball Association (NBA). Bryant enjoyed a successful high school basketball career at Lower Merion High School, where he was recognized as the top high school basketball player in the country. He decided to declare his eligibility for the NBA Draft upon graduation, and was selected with the 13th overall pick in the 1996 NBA Draft by the Charlotte Hornets, then traded to the Los Angeles Lakers. As a rookie, Bryant earned himself a reputation as a high-flyer and a fan favorite by winning the 1997 Slam Dunk Contest.

Bryant and Shaquille O'Neal led the Lakers to three consecutive NBA championships from 2000 to 2002. A heated feud between the duo and a loss in the 2004 NBA Finals was followed by O'Neal's trade from the Lakers after the 2003–04 season. Following O'Neal's departure Bryant became the cornerstone of the Los Angeles Lakers franchise. He led the NBA in scoring during the 2005–06 and 2006–07 seasons, setting numerous scoring records in the process. In 2006, Bryant scored a career-high 81 points against the Toronto Raptors, the second most points scored in a single game in NBA history, second only to Wilt Chamberlain's 100-point game in 1962. He was awarded the regular season's Most Valuable Player Award (MVP) in 2008. After losing in the 2008 NBA Finals, Bryant led the Lakers to two consecutive championships in 2009 and 2010, earning the NBA Finals MVP Award on both occasions.
