Humes was born on 18 March 1985, in Greenwich, London. He is the son of a Jamaican father and Anglo-Scottish mother and is the middle child of two brothers, Leon and Jackson and an uncle Naresh Ahir.
Humes started his music career in a band called VS which was created by Blue member Simon Webbe; however shortly after being formed and releasing an album, they split. Humes appeared in Holby City on the BBC for three years from 2000 to 2003 playing Robbie Waring for 14 episodes. At the age of 14, he starred in a children's programme called K-Club, which helped people with computers and how they work.
Oritsé Williams decided to get into the music business mainly. He was originally scouted for a number of boy bands but did not feel they were right, Williams decided to form his own boy band and, through friends, met Marvin Humes who had experience in R&B and pop music, being a part of VS in 2004. Next to join was Aston Merrygold, who was once cast in the ITV children's programme Fun Song Factory, because of his athletic ability. Last to join the group was JB Gill, for his "musical ear" and harmonies. They bonded, became friends and together they were called UFO (an initialism of Unique Famous Outrageous). They signed to Tracklacers developing a sound they then called "Jack the Lad Swing", combining the phrase "Jack the lad" and the urban music of new jack swing. While working their way into the music business, UFO instantly signed to Epic Records, before winning their first award in late 2007 at the Urban Music Awards for Best Unsigned Act thanks to their mash-up of "Stand by Me" by Ben E. King and "Beautiful Girls" by Sean Kingston. Shortly thereafter, they released their second single, "Slap Ya Elbow". The group give credit to 'DJ Triz' who produced one of UFO's first songs and helped them write it.
In 2008, UFO auditioned for the fifth series of The X Factor, but had to change their name because it was already being used by another group, so they decided to go with the name JLS (an initialism of Jack the Lad Swing, the style created with Tracklacers some months back). Following the elimination of girl groups Bad Lashes and Girlband in weeks one and two respectively, JLS were Louis Walsh's last remaining act in the competition, but throughout the live shows the judges called them the best band to come out of The X Factor. In week 7, JLS were in the bottom two along with Rachel Hylton. However, they survived thanks to votes from Walsh, Cheryl Cole and Simon Cowell. Cowell stated when casting his deciding vote that JLS did not deserve to be in the bottom two. In week 8, JLS performed "...Baby One More Time" and received negative comments from two of the four judges, with Cowell saying "at the moment you're out", but after their second performance, "You Light Up My Life", Cowell commented that they were "back in the race" and that they could "have a hit record" with the performance.
In week 9, JLS performed "Umbrella" and "I'm Already There". Cowell then predicted they would win the competition. They made it to the final and performed their own version of the winner's song, "Hallelujah", which the other finalist Alexandra Burke also performed. The public voted for the second time that night and Burke won the competition, JLS becoming the runners up. They were the fourth band to make the final. Following their success on The X Factor, Cowell's record company, Syco, announced that they were to sign JLS with an advance payment of £75,000. The Sun later reported on 20 January 2009 that Cowell had revoked this offer, having instead decided to focus on Alexandra Burke. JLS's manager thought the band would be well suited to Epic Records, with whom they signed a record contract in January 2009.
Following their appearance on The X Factor, JLS signed to Epic Records. Their first two singles "Beat Again" and "Everybody in Love" both went to number one on the UK Singles Chart. The band's self-titled debut album was released on 9 November 2009, and has since sold over 1 million copies in the UK. JLS won the awards for British Breakthrough and British Single ("Beat Again") at the 2010 BRIT Awards. They also won several awards at the Mobo awards for Best song for "Beat Again" in 2009 and also Best Newcomer in the same year. In 2010, they won the MOBO Awards for Best UK act and Best Album. They also went on to win their fifth MOBO Award in 2012 by winning Best Video for "Do You Feel What I Feel?". They won the title of the UK's hardest-working band for two constitutive years, in 2011 and 2012.
In 2010, JLS signed a record deal in the United States with Jive Records, and released "Everybody in Love" as their debut US single, but it failed to chart. "The Club Is Alive", the lead single from their second studio album, was released in the UK in July 2010, and earned the band their third number-one on the UK Singles Chart. Their single "Love You More", the official single for Children in Need in 2010, was the group's fourth UK number one. Their single "She Makes Me Wanna" featuring Dev was their fifth UK number one. As of 2012, their debut album and single has been named one of The X Factor's top ten biggest-selling debut singles and albums. JLS have sold more than 10 million records worldwide. As of 2013, they are the sixteenth richest reality TV stars in the UK, with an estimated fortune of £6 million per member, totalling £24 million.

On 24 April 2013, it was announced that the band were to split after their fifth album and tour. They released their last book as a band called Forever and a Day, One Last Goodbye X on 24 October 2013.
