Songfacts®:

• This song finds Shakira and Beyoncé talking about how the same man told each of them that she was the one and only. Instead of starting a fight or plotting to get back at the guy, they decide he isn't worth it, and to ignore him. Beyoncé considers it a female-empowerment song.
• On the week of April 7, 2007 this made the biggest ever leap in the Billboard Hot 100 when it rose 91 positions to land at #3. It broke the previous record, which was the 95-7 jump of "Smack That" by Akon featuring Eminem on the chart dated October 14, 2006.
• Beyoncé recorded this herself before asking Shakira to sing on it with her. The song has a Latin flavor and some Spanish lyrics that suited Shakira well.
• Though this only reached #3 in America, the song was a smash hit internationally, topping the charts in 32 different countries, including the UK, France, Germany, Italy and New Zealand.
• Mikkel S. Eriksen, half of the songwritng/production duo Stargate, who co-created the tune, said the project was a lesson in simplicity. "This song is very simple," he told Sound on Sound. "Most of the time we have more chords in a song, because we find it hard writing a great song on just one chord. But if you do it right, you can make it work, and this song is an example."
• Beyoncé and Shakira, who recorded their parts separately in their respective studios, met to film the music video. Directed by Jake Nava, the clip finds the singers emerging from a smoky background as they individually perform their parts, mirroring each others' outfits and dance moves, until they finally meet for a sultry belly-dancing session.
  
  The video won the MTV Video Music Award for Most Earthshattering Collaboration in 2007.
• Along with Beyoncé and the Stargate production team, this song was written by the team of Ian Dench and Amanda Ghost, who also contributed to the I Am... Sasha Fierce track "Disappear." Dench is best known as the guitarist in EMF, who had a huge '90s hit with "Unbelievable."
• This was nominated for Best Pop Collaboration With Vocals at the 2008 Grammy Awards, but lost to "Gone Gone Gone (Done Moved On)" by Robert Plant and Alison Krauss.
