"Do It" is a popsong by Canadian recording artist Nelly Furtado for her third album, Loose (2006). It was produced by Timbaland and Nate "Danja" Hills. It features a prominent influence of 1980s dance-pop music and sexually suggestive lyrics, in which the song's protagonist asks a lover to satisfy her physically.

Alongside a remix featuring rapper Missy Elliott, the song was released as the fifth single from Loose in North America in mid-2007, and Furtado co-directed the accompanying music video. "Do It" reached the top twenty in Canada and was a number-one club hit in the United States, where it became Furtado's lowest peaking single on the Billboard Hot 100; it reached higher positions on charts on mainland Europe.

In January 2007, it was revealed that Timbaland plagiarized the synth line in "Do It" from an earlier track by Finnish demoscener Janne Suni—for more information, see 2007 Timbaland plagiarism controversy.

Furtado has credited the influence of 1980s musicians such as Blondie, Madonna, The Police, Prince and Talking Heads on Loose, saying that the album's creative team "were picking up on some of the more surreal, theatrical elements of '80s music, the stuff that puts you in sort of a dream state. There's a mysterious, after-midnight vibe to this album that's extremely visceral. I want people to escape into the music and indulge their most animalistic impulses." Referring to the sexually suggestive lyrics in "Do It" and other songs on Loose, Furtado cited the influence of what she described as "the assertive female sexuality of '90s hip-hop, from Queen Latifah to MC Lyte, Yo-Yo, Salt-N-Pepa, TLC. They were sexy, smart and creative—strong women in control. That's what I like about the sexual content on Loose: It's very organic."

Jennifer Lynn Lopez (born July 24, 1969) is an American actress, businesswoman, dancer and recording artist. Often referred to as J.Lo, she is reportedly the highest earning actress of Latin descent. Born and raised in The Bronx, New York, she enrolled in singing and dancing classes as a child and grew up in a musically influenced household. She started her career as a fly girl on the television comedy program In Living Color and a back-up dancer for Janet Jackson. Lopez gained recognition in the action-thriller Money Train (1995). Her first leading role was in the biographical film Selena (1997), which was her breakthrough role, earning her an ALMA Award for Outstanding Actress and Golden Globe nomination. She earned her second ALMA Award for her performance in Out of Sight (1998), which made her the highest-paid Latin actress. She has since appeared in various films including The Cell (2000), The Wedding Planner (2001), Maid in Manhattan (2002), Shall We Dance? (2004), Monster-in-Law (2005), The Back-up Plan (2010) and What to Expect When You're Expecting (2012).

James Todd Smith (born January 14, 1968), better known as LL Cool J (an abbreviation for Ladies Love Cool James), is an American rapper, entrepreneur, and actor from Bay Shore, New York. He is known for romantic ballads such as "I Need Love", "Around the Way Girl" and "Hey Lover" as well as pioneering hip-hop such as "I Can't Live Without My Radio", "I'm Bad", "The Boomin' System", and "Mama Said Knock You Out". He has released thirteen studio albums and two greatest hits compilations, including 2008's Exit 13, the last for his record deal with Def Jam Recordings. He has also appeared in numerous films, and currently stars as NCIS Special Agent Sam Hanna on the CBS crime drama television series NCIS: Los Angeles.

As he grew older, Smith found a way to escape the effects of his abuse, and his bullying attitude: hip-hop music. He fell in love with it at the age of nine, and by 11 he was writing lyrics and making his own songs with some DJ equipment his grandmother gave him to stop him riding motorcycles or doing karate. Before too long, LL was an established member of the Hip-Hop community in his area. He gained notoriety through his many rap battles against well-established MCs, including the battle against Chicken and Porn that rocketed him to fame.
