Colden Rainey Swindell (born June 30, 1983) is an American country music singer and songwriter. He has written singles for Craig Campbell, Thomas Rhett, Scotty McCreery, and Luke Bryan, and has released three albums for Warner Bros. Records Nashville.

Machine Gun Kelly released four mixtapes between 2007 and 2010 before signing with Bad Boy Records. He released his debut studio album, Lace Up, in 2012, which peaked at number four on the US Billboard 200 and contained his breakout single "Wild Boy" (featuring Waka Flocka Flame). 

Machine Gun Kelly released his fifth album, Tickets to My Downfall, in 2020; it marked a complete departure from hip hop and entry into pop punk. It debuted at number one on the Billboard 200, the only rock album to do so that year, and contained the single "My Ex's Best Friend",

Machine Gun Kelly had his first starring role in the romantic drama Beyond the Lights (2014), and since appeared in the techno-thriller Nerve (2016), the horror Bird Box (2018), the comedy Big Time Adolescence and portrayed Tommy Lee in the biopic The Dirt (both 2019).

In his new Hulu documentary "Life in Pink," Machine Gun Kelly opens up about a dark mental health episode he recently went through.

"Life in Pink," now streaming, offers an "in-depth look at the dramatic highs and lows" the platinum-selling rap rocker has navigated while "chasing music’s top spot," according to the official Hulu website.

At one point in the film, Kelly (real name Colson Baker) goes into harrowing detail about the toll his father's death took on his mental health. The "my ex's best friend" singer said his father died the same day his fourth album "Hotel Diablo" dropped in July 2019.

Kelly said his inner turmoil culminated in a tense conversation with fiancée Megan Fox, who was his girlfriend at the time. 

The 32-year-old singer said the intense episode, coupled with conversations he had with Fox and his 12-year-old daughter Casie, was a wake-up call for him "to kick the drugs for real this time."

Kelly has previously opened up about his history of drug use, telling Dave Franco in a 2020 Interview magazine discussion that therapy helped him tackle the "intense" dichotomy of his artistic persona Machine Gun Kelly and his personal identity.
