"Want U Back" is a song by English singer Cher Lloyd from her debut studio album, Sticks and Stones (2011).

On 15 December 2011, it was announced that "Want U Back" would be released as the third single from Lloyd's debut album, Sticks and Stones.

[5] In an interview with Metro News's Daniella Graham, Lloyd stated that she hoped the track would help her get into the American market, saying "I don’t expect anyone to know who I am because I live in the UK.

[8] The version with Snoop Dogg was released as a bonus track to Sticks and Stones on Lloyd's online store and on the Japanese edition of the album.

Nick Levine from BBC Music wrote a positive review, commenting: "She's a natural and charismatic vocal presence, so much so that Want U Back even creates a recurring hook from – how to put this?

"[13] Jon O'Brien from AllMusic wrote that the song is "an infectious example of cutesy pure pop that recall Britney before she lost her innocence.

"[14] Alex Denney from NME considered it "a sassy bit of bubble-drunk pop from Britney songwriter Max Martin.

"[15] Danner had previously written in another NME review that the song is "a peachy-keen pop number that goes pining after an ex, Cher drawing comfort from the fact that, even if her beloved is going out with someone else now, at least they’re only getting sloppy seconds.

"[17] Lewis Corner of Digital Spy gave the song a positive review stating: "Truth be told, it's quite refreshing for an artist to embrace their perceived public image, but the joke is really on us.

"[12] X. Alexander of Idolator said "Instead of blasting us with that 'Swagger Jagger', she's coming at us with the uber-catchy 'Want U Back' — a good choice, since we haven't been able to get it out of our heads since we first heard it.

"[18] David Griffiths from 4Music praised the track, writing: "It might not sound a million miles away from Miley Cyrus' 'Party in the USA', but it's got Cher's stamp all over it.

"[19] Bradley Stern from "MuuMuse" commented: "It is one of the album’s catchiest, cutest moments–even if Lloyd’s gritting her teeth and clenching her fists with rage.

[...] Lloyd sings incredulously on the bouncing electro-pop beat, dissing the chick’s jeans and denying all charges of jealousy in the process.

[33] It was last seen on the Billboard Hot 100, close to exiting the top 75, later moving to "recurrent status" after 20 weeks if fallen below position number 50.

These include Lloyd pouring a water bottle over her ex while they're at the park, and in another scene, she throws popcorn over them at a movie theater.

Astro makes an appearance to rap his verse, and the video ends with Lloyd imitating a helicopter.

[39] This new video shows Lloyd confronting her ex-boyfriend and his new girlfriend in California diner Cadillac Jacks, while performing the track on the restaurant's counter top.

On 30 August 2012, Lloyd performed the song, along with her next single, "With Ur Love", on Today to an audience of hundreds of fans.
