Beyoncé ft. Sean Paul | Baby Boy (2003)

Both artists co-wrote the song with Robert Waller, Jay-Z, and Scott Storch, who produced it with Beyoncé. Containing a lyrical interpolation of "No Fear" by hip hop group O.G.C, "Baby Boy" is an R&B and dancehall song with Caribbean and Asian influences; its lyrics detail a woman's fantasies.

The song was released as the second single from the singer's debut studio album Dangerously in Love on August 3, 2003, through Columbia Records and Music World Entertainment. "Baby Boy" topped the US Billboard Hot 100 for nine consecutive weeks and was Beyoncé's longest-running number-one single until 2007, when it was surpassed by "Irreplaceable".

It reached the top ten in many countries and was certified double platinum by the Australian Recording Industry Association (ARIA), and platinum by the Recording Industry Association of America (RIAA). It also reached the top 10 in Australia, Belgium, Denmark, France, Germany, Hungary, Ireland, the Netherlands, New Zealand, Norway, Spain, Sweden, Switzerland, and the United Kingdom.

The song's music video was directed by Jake Nava and mostly shows Beyoncé dancing in various locations. "Baby Boy" has remained a staple of Beyoncé's concert set lists. The American Society of Composers, Authors, and Publishers (ASCAP) recognized it as one of the most performed songs of 2004.

In 2005, American singer-songwriter Jennifer Armour filed a copyright infringement lawsuit claiming that the song had used the primary musical hook from her song "Got a Little Bit of Love for You". The suit was later dismissed.
