Dominick Antron Wickliffe (born September 23, 1976), better known by his stage name Kxng Crooked, (stylised as KXNG Crooked and pronounced "King Crooked"; formerly Crooked I) is an American rapper from Long Beach, California. He formed the hip hop supergroup Slaughterhouse with fellow rappers Joe Budden, Joell Ortiz and Royce da 5'9" in 2008, with whom he released two studio albums — Slaughterhouse (2009) and Welcome to: Our House (2012) — before disbanding in 2018. The latter was released by Eminem's Shady Records, an imprint of Interscope Records, although Wickliffe's solo albums have been released independently.

He founded the record labels Dynasty Entertainment and C.O.B. Digital, and is Senior Vice President of Treacherous Records. Prior, he signed with Virgin Records and Death Row Records, but released no projects with both labels. In 2022, he formed the rap duo Crook and Joell with former Slaughterhouse bandmate Ortiz; they have released three studio albums.

Around the age of seventeen, Crooked I started an independent record company called Muscle Records with professional football players Chucky Miller and Leonard Russell, also from Long beach. It's not known how many songs were recorded, and the music recorded during this period still remains unreleased. This is when he caught the attention of Noo Trybe/Virgin Records, and landed his first record deal in 1995.

Crooked I originally got his start appearing on compilations released by Big C-Style's record label, 19th Street Records, such as 19th Street LBC Compilation and Straight Outta Cali. He also appeared on the soundtracks of movies such as Ride and Caught Up, where he collaborated with Snoop Doggy Dogg, Tha Eastsidaz, and The Luniz. At the time, Crooked I was still signed to Noo Trybe/Virgin Records, which handled distribution for 19th Street Records. Business was going well, but for unknown reasons, Virgin Records decided to get rid of its urban division, and Crooked I was out of a record deal.

Wickliffe was later contacted by Big C-Style and Daz Dillinger to form DPG Records, which was originally going to be a sub-label under Death Row Records at the time. Crooked was going to be 20% owner of the label, and the first act released as well. Daz left Death Row Records to run DPG Records independently, but rather than go with Daz, Crooked was trying to figure out his options.

Crooked I also had talks of signing to Dr. Dre's Aftermath imprint, but Dre wanted to release Chronic 2001 and Eminem's Marshall Mathers LP before releasing Crooked. He also had talks with other major record labels who wanted to sign him, but they too were waiting for Dr. Dre's Chronic 2001 album to be released before they would consider signing another West Coast MC. It was around this time that Crooked I re-negotiated the original deal he had with DPG Records/Death Row Records as a solo artist deal with just Death Row Records.

While on Death Row, Crooked I appeared on a number of compilations, such as Dysfunktional Family, and appeared on various releases, such as Ja Rule's The Last Temptation, and 2Pac's Nu-Mixx Klazzics. He also recorded two albums, Untouchable and Say Hi To The Bad Guy, both of which were unreleased due to various label issues and industry politics. He did manage to release a mixtape along with Death Row's then in-house producer, Darren Vegas, called Westcoasanostra Vol. 1 in the Spring of 2003.

By 2004, Crooked I's album had not been released, Suge Knight was constantly in and out of jail, and Crooked I's contract with Death Row Records had expired by November 2003. He left Death Row in early 2004 to start his own label, Dynasty Entertainment. It was not long after that when Crooked I signed a distribution deal with Treacherous Records/Universal, but more legal trouble from Death Row surfaced so Crooked I had to stop production for his then titled debut album, Mama's Boy, which was actually going to be the name of Crooked's second release under Death Row Records. Later on the title of the album changed to Mama's Boy Got a Loaded Gun.
