"Bleeding Love" is a song recorded by British singer Leona Lewis for her debut studio album, Spirit (2007).

[6] "Bleeding Love" reached number one in over 35 countries,[7] including France, Germany, Japan and the United States, making it only the second single in history to achieve this feat, Elton John's "Candle in the Wind '97" being the first.

[13] "Bleeding Love" was nominated for Record of the Year and Best Female Pop Vocal Performance at the 51st Annual Grammy Awards.

[15] Meanwhile, in February 2007, OneRepublic's frontman Ryan Tedder and singer Jesse McCartney had written "Bleeding Love" for the latter's third studio album, Departure (2008).

[17] Despite his own reality television background, Tedder had previously made the decision not to work with contestants from American Idol, but he had not heard of The X Factor, and on being shown a website about Lewis, he thought that "her voice just sounded unreal," saying that "from a writer's perspective, this girl – with or without a television show – has one of the best voices I've ever heard.

"[18] On hearing that Cowell was looking for songs for Lewis' debut studio album, Tedder rearranged "Bleeding Love", changed the key and tailored it to suit her voice.

[18] After the success of Lewis' version, the song was re-recorded by McCartney, being included as a bonus track on the international edition of Departure.

Lewis performed the song live on the fourth series of The X Factor on 20 October 2007,[30] and also made appearances on several other television and radio shows such as T4, GMTV and Loose Women.

Lewis performed the song at the Sanremo Music Festival in Italy on 29 February 2008, and on the German entertainment television show Wetten, dass..?

Showbiz Spy described it as "emotionally fuelled," and opined "this track perfectly showcases Leona's impressive vocal prowess and from the moment she opens her mouth we are instantly reminded about her amazing voice, capable of heart stopping intensity and a playful light touch.

"[33] Digital Spy's review of the song gave it four out of five stars, saying it is "easily the best single to be released by an X Factor star," and describing it as "a brilliantly smart pop record, managing to offer the lovelorn balladry that Lewis' X Factor fans are no doubt craving, while also suggesting a hint of street cred in the form of some beefy, vaguely modish beats.

[35] However, BBC America's reviewer expressed that "the inventive percussion can't stop 'Bleeding Love' from sounding dated, like filler on some long-lost, late '90s Mariah Carey album.

"[36] Billboard's review by Singles Review editor Chuck Taylor for "Bleeding Love", the first ahead of the song's release in the United States, stated it was "a colossal and timeless debut," going on to say "not only a one-listen harmonic show-stopper, it is also hip, soulful, beat-rippling and an undeniable vocal tour de force.

[41] Although the award was won by Take That's "Shine", it was announced that "Bleeding Love" had received the second-highest number of public votes.

On 3 December 2008, "Bleeding Love" was nominated for Record of the Year and Best Female Pop Vocal Performance at the 51st Annual Grammy Awards, but lost to Robert Plant and Alison Krauss' "Please Read the Letter" and Adele's "Chasing Pavements", respectively.

[46] In the United Kingdom, "Bleeding Love" debuted at the top of the UK Singles Chart on 28 October 2007 ― for the week ending dated 3 November 2007.

[50] The single went on to sell 218,805 copies in its first week, gaining the biggest one-week sales in 2007, a feat it maintained until "When You Believe" by Leon Jackson ― her successor as winner of the UK X Factor – was released in December 2007.

On 10 February 2008, the single received a platinum certification by the Australian Recording Industry Association (ARIA), with sales of over 70,000 copies.

[57] In New Zealand, Lewis became the first British female artist to have a number-one single since the Sugababes' "Push the Button" topped the chart in January 2006; it stayed at number one for five weeks.

"Bleeding Love" was a success on radio stations around the world, reaching number one on the Airplay Charts of the United Kingdom, Switzerland, Germany,[60] Australia,[61] New Zealand, Luxembourg,[62] Slovakia,[63] Latin America,[64] Estonia[65] and Japan.

[48] In the United States, "Bleeding Love" was released digitally on 18 December 2007,[68] and debuted on the Bubbling Under Hot 100 chart at number 11.

[48] It also topped the Billboard component charts, including the Hot Digital Songs[70] and Adult Contemporary, where it spent 52 weeks.

[71] Lewis is the third British female artist to have a number-one hit with a debut US single, following Petula Clark with "Downtown" and Sheena Easton with "Morning Train (Nine to Five)".

[73] On Billboard's Hot 100 Year-End chart for 2008, "Bleeding Love" was ranked at number two, only behind "Low" by Flo Rida featuring T-Pain.

Certified platinum by the Recording Industry Association of America (RIAA), the single has sold 4,589,000 digital downloads in the United States as of December 2013.

The treatment for the video was written by Tedder,[78] and centres on a storyline involving Lewis arguing with her boyfriend, played by model Nicholas Lemons.
