It was written and produced by Ryan Tedder, with Leonard Caston, Anita Poree, and Frank Wilson receiving writing credits for the sample of Eddie Kendrick's "Keep on Truckin".

The music video directed by David LaChapelle finds Lopez rescuing a little boy who is forced to work in the kitchen of an S&M nightclub.

[10] A remix featuring American rapper Ludacris was also released on both Vinyl single[11] and as a bonus track of Brave.

[12] "Do It Well" was written and produced by Ryan Tedder, with Leonard Caston, Anita Poree and Frank Wilson receiving writing credits for the sample of Eddie Kendrick's number-one single "Keep on Truckin' (1973).

"[16] Alex Fletcher from Digital Spy gave to the song 4 out of 5 stars, commenting that "It's brassy, sassy, (although certainly not classy) and it's here to replace Beyoncé's 'Crazy In Love' as everyone's favourite guilty dancefloor pleasure.

The tracks got that "classic" J-Lo feel, huge strings and horns pared over funk-based percussion, with just a dash of Latin flavor thrown in.

Music wrote that the song "may not be prime club material, but they all come with choruses and grooves guaranteed to make the housework go with a swing.

"[19] On the other hand, Michael Slezak from Entertainment Weekly wrote a mixed review, writing that "it finds Lopez's voice as tinny and feeble as ever, singing lyrics that may have sounded believable back in the early ’90s days of In Living Color, but now come off as a preposterous attempt to 'keep it real'.

"[20] But he praised "the melody's as easy as it is catchy (perfect as "Jenny from the Block" for inebriated karaoke), and the beat demands a sumptuous choreographical feast of a video.

"[21] Eric Henderson from Slant Magazine wrote that the song "is a fairly imaginative reworking of one of the many string breaks from Eddie Kendricks's "Keep On Truckin'.

[37][38] In Italy, it went on to debut at number 2, becoming Lopez's seventh top-ten hit, remaining at the top ten for other three consecutive weeks.

[40] "Do It Well" was heavily promoted with performances of the song occurring during the Good Morning America Summer Concert Series, Late Show with David Letterman, Fashion Rocks 2007, Saturday Night Divas and Dancing with the Stars.
