Perfectionist is the debut studio album by English singer Teddy Sinclair, under the name Natalia Kills.

Sinclair worked with musicians including Fernando Garibay, Jeff Bhasker, and Martin Kierszenbaum, and created a concept album based on perfectionism.

The album spawned four singles—"Mirrors", "Wonderland", "Free" and "Kill My Boyfriend"—which were generally successful in Europe and were accompanied by music videos.

Kills initially pursued an acting career, appearing in some TV and radio series including All About Me and The Archers; however, in her hometown of Leeds, she developed an interest in hip hop music.

In 2007, she relocated to Los Angeles;[5] the next year, she lent guest vocals to French artist M. Pokora's song "They Talk Shit About Me", and changed her stage name to Natalia Cappuccini, under which she self-released an extended play (EP) titled Womannequin.

After it was posted in American blogger Perez Hilton's blog, Kills' MySpace received a high number of views, and she reached the top of the social network's unsigned artists chart.

[3] While shopping, she was noticed by a man due to her clothing, and gave him her website address; he subsequently introduced her to a DJ, who took Kills to the American musician will.i.am's house.

[8] Kills started to prepare material for Perfectionist after establishing her record deal with will.i.am, who served as an executive producer for the album.

"[10] Kierszenbaum praised Kills' work ethic during the recording sessions, stating that she would focus simultaneously on the melodic and lyrical structure of song, as well as its soundscape.

[3][15] Its opening track, "Perfection", runs for thirty seconds and sees a "robotic-sounding" therapist listing Kills' flaws.

[17] A track including a bassline, piano, club beats and synths, "Free" samples "Wuthering Heights" by Kate Bush.

[3][17] "Disco–pop" track "Mirrors" references sadomasochist sexual practices, while portraying Kills with a dominatrix-like persona; it contains electric guitars, and a bassline which Robert Copsey from Digital Spy compared to that of Eurythmics' "Sweet Dreams (Are Made of This)".

[16][19] Writing for Consequence of Sound, Alex Young opined that the song discusses "the duplicity of identity, hubris, and objectification".

On "Acid Annie", Kills plots a revenge on an ex-boyfriend, while on the synthpop track "Superficial", she confronts her "consumptive impulses" and appreciation of "finer things.

"[3][14][16] "Broke" sees Kills talking about money; "Nothing Lasts Forever" is a duet with Bhasker, who performs under the alias of Billy Kraven.

[32] Despite not having been included in the album, "Activate My Heart" was released as its second promotional single on 13 April 2010, while an accompanying visual was uploaded on 17 December.

[35][36] An accompanying music video was released on 1 December 2010, featuring Kills being dragged into a mirror and subsequently exploring the concepts of vanity, control and sex.

[39][40] Doubet was commissioned to direct its music video, which sees Kills being forced into a mansion, being fed a cooked heart and ultimately climbing up a table, leading to chaos and violence inside the house.

[47] The first episode starts with Kills furiously walking with a revolver in direction of a blonde man; she later ties him up on a bed, as he screams and tries to resist.

She manages to strangle the leader of the group, and later leaves a message for her anonymous friend, warning him that her face is being distributed on wanted posters.

The camera shifts to a field where Kills makes a man jump from a cliff, by playing a game of "cold, warm and hot" with him.

Jon O'Brien from AllMusic summarised it as "formulaic and gimmicky", and observed that the music was secondary to Kills' attempts of establishing a mature image.

[16] AltSounds staff member Jack Stevin deemed it "disappointing" and unfocused, writing that Kills was not in control of the album and that she had an "air of pretension around" her.

"[69] Writing for Consequence of Sound, Alex Young noted that Kills expressed herself better as a musician through music videos, and surmised that "not all the songs on Perfectionist hit their mark".

[14] musicOMH writer Blair Kelly characterised the album as imperfect, "uninspired, unoriginal and obvious" while negatively comparing it to the works of American singer Lady Gaga.

"[77] That year, Corner hailed Perfectionist as "one of the most underrated pop collections in recent memory", and Idolator's Sam Lansky opined that although it had "killer" choruses, the album suffered from excessive similarities to other artists.
