Let's Do It may refer to:

"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."

The imperative mood (abbreviated IMP) expresses commands or requests as a grammatical mood. These commands or requests urge the audience to act a certain way. It also may signal a prohibition, permission, or any other kind of exhortation.

Formulation of the English imperative simply uses the bare infinitive form of the verb. The infinitive form usually corresponds to the second-person present indicative form, with the exception of the verb be. The subject of these sentences is usually understood as you (the second person) except in the case of "Let's" which implies first person and at least a second person. Other languages such as Latin, French and German have several inflected imperative forms, which can vary according to grammatical categories such as:

For instance, Latin regular forms can exist:

Some consider this richness of forms useful for a better understanding, particularly because no subject pronoun normally specifies with the imperative.

The use of the imperative mood be seen as impolite, inappropriate or even offensive in certain circumstances. Commonly, polite speech will instead express the same thing as a question or statement, such as:
