No Boys Allowed by Keri Hilson

No Boys Allowed is the second studio album by American recording artist Keri Hilson. It was released on December 17, 2010, by Mosley Music and Zone 4 Records. On the album, Hilson has reunited with Timbaland and Polow da Don, who executively produced the album, as they did with her debut release. Hilson also worked with several other producers and songwriters, including Ne-Yo, John Legend, StarGate, Bei Maejor and Boi-1da, among others. Meanwhile, Chris Brown, Rick Ross, Kanye West, J. Cole, Nelly and Timbaland, are serving as featured guest vocals. Musically, No Boys Allowed is an R&B album, which incorporates elements of pop, soul, electro and dancehall into various songs. Upon its release, the album has received mixed reviews from most music critics, and peaked at number eleven on the US Billboard 200, selling 102,000 copies in its first week. Although it sold 8,000 copies more than her debut album, In a Perfect World... (2009), it failed to match that album's debut chart position of number four. No Boys Allowed also debuted on the US Top R&B/Hip-Hop Albums chart at number seven and at number ten on the UK R&B Albums Chart. The album's lead single, "Breaking Point" was released in the United States on September 7, 2010 and peaked at number forty-four on the US Hot R&B/Hip-Hop Songs chart. The second single "Pretty Girl Rock", was released on October 12, 2010, and peaked within the top ten on the Hot R&B/Hip-Hop Songs chart and the top fifteen in New Zealand. Other two singles, "One Night Stand" and "Lose Control (Let Me Down)" were released for radio in March and May 2011, respectively.
