P Square is made up of two members called Peter and Paul Okoye.
The story of P Square began in St. Murumba College, a small Catholic school in Jos, Nigeria.. Identical twins Peter and Paul joined their school music and drama club where they began singing, dancing, and miming songs by MC Hammer, Bobby Brown and Michael Jackson.
They later formed an a cappella quartet called MMPP (Michael, Melvin, Peter and Paul). Drawing inspiration from their music idol Michael Jackson, they began break dancing, and formed the group called "Smooth Criminals" in 1997. Their artistic talent and precise dance routine soon made them household names in the city of Jos, where they performed at school functions and other occasions.
Later in 1999, Peters and Paul returned to music school to develop their skills on keyboard, drums, bass and rhythm guitar. Their work includes the soundtracks for films like Tobi, Mama Sunday, Moment of Bitterness, Evas River.
Academic pursuits led them to the University of Abuja later that year, where they were admitted to read Business Administration. The Smooth Criminals disbanded when its members were dispersed to northern universities in Nigeria. Subsequently Peter and Paul formed their own group, variously called "Double P", "P&P", and "Da Pees", until they eventually settled on "P Square".
In 2001, P Square won the "Grab Da Mic" competition, and hence Benson & Hedges sponsored their debut album, titled "Last Nite", which was released under Timbuk2 Music Label.
They are managed by Bayo Odusami aka Howie T, a seasoned concert promoter and the CEO of Adrot Nigeria Limited. P Square was nominated as "Most Promising African Group" in the Kora Awards three months after the release of their debut album. They eventually won the 2003 Amen Award for Best R&B Group.
P Square released their second album, "Get Squared" under their own label, Square Records. This album is marketed nationwide by TJoe Enterprises, although they are still managed by Howie T of Adrot Nigeria Limited.
The video for the second album, "Get Squared", held the #1 position on the MTV Base chart for four straight weeks.
Since then, they have released two hit albums; Tempted to watch and Game over (2007).
Game over is very popular right now and is giving the group major airplay with its featured songs “The game is over,” “Do me,” “Roll it,” “No one like you,” “Ifunanya,” “Am I still that special man,” and so many more.
P Square has won various awards including the  Hip Hop World Awards 2006 for Best R&B Album (Get Squared), Hip Hop World Awards 2006 for  Best Music Video (Get Squared), Hip Hop World Awards 2006 for Album Of The Year (Get Squared), Hip Hop World Awards 2006 for Song Of The Year (Bizzy Body), City Mag 9th Awards Show (2006) for Best Hip Hop Group, Nigerian Music Awards (NMA) 2006 for Album of the year (Get Squared) and Nigerian Music Awards (NMA) 2006 for Music Video of the year (Get Squared). Also, P Square has been nominated at the KORA Awards 2003 for Most Promising African Group and  at the MOBO Awards 2006 for the Best African act.
The group has performed alongside various international names including Ginuwine, Sean Paul, Akon and so many more.
