No Boys Allowed is the second studio album by American recording artist Keri Hilson, first released on December 17, 2010 through Mosley Music and Zone 4 Records. On the album, Hilson is 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, J. Cole, Nelly, Kanye West and Timbaland all have featured guest vocals. Musically, No Boys Allowed is an R&B album, which incorporates pop, soul, electro and dancehall into the songs.
The album received mixed reviews from most music critics, and peaked at number eleven on the U.S. 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..., it failed to match that album's debut chart position of number four. No Boys Allowed also debuted on the 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 U.S. 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.
