The Naked Truth is the fourth studio album by American rapper Lil' Kim, released on September 27, 2005. The album was released on the first day of Kim's sentencing, in which she went to jail for nearly a year on perjury charges. It was her last studio album released by Atlantic Records before deciding to part ways in 2008. Two official singles were released from the album: "Lighters Up" as the lead single released in September 2005 while "Whoa" served as the second and final single in February 2006. The Naked Truth remains the only album by a female rapper to be rated five mics by The Source.
The first single taken from the album was "Lighters Up". It was released on September 13, 2005 and was a commercial success, peaking at number 31 on the Billboard Hot 100. The second, and final, single from the album was "Whoa". Released on February 7, 2006, it was less successful than its predecessor and failed to make the Hot 100. It did manage to chart in the UK, peaking at number 43.
The first promo single taken from the album was "Shut Up Bitch". For the release the title was censored to "Shut Up". Released to radio on July 12, 2005, the song served as a promotional single for the album and peaked at number 73 on the Billboard Hot R&B/Hip-Hop Songs chart. It can be heard at the start of the "Lighters Up" music video. The second promo single was "Spell Check". It was released to US radio as a promo single for the album in December 2005, alongside "Whoa". The song was promoted in the music video for "Whoa" with Kim rapping the first verse and chorus near the end.
The album received generally positive reviews and was given a score of 66 out of 100 by Metacritic, with 5 star ratings from The Source (in which she became the first female rapper to ever receive 5 mics), Vibe Magazine, and The Village Voice and less than favorable reviews from The New York Times and AllMusic. Blender gave the album four stars, calling it her "strongest work since her pheromone-thick 1996 debut". While the album did receive several 5 star ratings, Pitchfork journalist Jess Harvell, who gave the album a positive 7.8 rating stated "The Naked Truth may be better than 80% of the other rap albums to be released in 2005, but that doesn't make it another Ready to Die."
The Naked Truth debuted at number six on the Billboard 200 and at number three on the Top R&B/Hip-Hop Albums chart, selling 156,000 copies in its first week. The album became her shortest run on the albums chart, falling out of the 200 albums chart after eight weeks. As of 2010, it had sold 800,000 copies in the United States and over 2 million copies worldwide .
