"Come on Over Baby (All I Want Is You)" is a song recorded by American singer Christina Aguilera for her 1999 self-titled debut studio album.

Released as the album's fourth and final single on July 11, 2000, by RCA Records, it was the first song over which Aguilera was given significant creative control.

"Come on Over Baby (All I Want Is You)" was written by Johan Åberg and Paul Rein, with Aguilera, Ron Fair, Chaka Blackmon, Raymond Cham, Eric Dawkins, Shelly Peiken and Guy Roche contributing to a re-recorded version.

The accompanying music video for "Come on Over Baby (All I Want Is You)" saw Aguilera experiment with her image, beginning an evolution of reinventions seen in the ensuing years of her career.

The original album version has no bridge, so it had previously been performed live with an interlude that sampled the disco classic "Got to Be Real" by Cheryl Lynn.

[8] Aguilera helped write the song's controversial and slightly sexual rap section from the re-recorded version.

[2][9] This rap (and also a section in the second verse in which Aguilera discusses sexuality and a man's hands on her body) caused Radio Disney to ban the song initially, as it had done with "Genie in a Bottle".

[3][2] The radio mix of the song is hip hop-influenced, featuring a rap verse written by Aguilera herself, and was deemed the most "sexual" track on the singer's debut album.

[2][9] A music-related website, Can't Stop the Pop, noted that "thematically it sits close" to the singer's fourth studio album Stripped (2002).

Billboard's Mia Nazareno called the song a "Radio Disney-approved bop" and complimented its "addictive", "danceable" sound.

[15] Chris Malone, also from the Billboard magazine, noted that it was the singer's "first song where she was given significant creative control", and compared it to Whitney Houston's early recordings.

"[6] Music critic Kenneth Partridge praised the re-recorded version of the single as "slightly rougher and randier" [than the original].

[17] In 2005, "Come on Over Baby" was listed in the book titled The 7,500 Most Important Songs of the Rock and Roll Era: 1944–2000 by Bruce Pollock, where the author called Aguilera "the voice of a new generation".

[24] Jamie Tabberer from the Attitude magazine ranked "Come on Over Baby" at number ten on the list of Aguilera's seventeen best songs ever,[25] Nicole Hogsett of Yahoo!

placed it at number six on a similar list,[9] and Mike Wass, writing for Idolator, called it a "bubblegum pop of the absolute highest caliber".

[36] The original version of "Come on Over Baby" also achieved commercial success in Latin America, reaching the top spot in Guatemala and Venezuela.

The music video for "Come on Over Baby (All I Want Is You)" premiered on MTV and VH1 the week ending on July 24, 2000, and was an instant hit, shooting to No.

In the second leg of her "Christina Aguilera: In Concert", where she visited Puerto Rico, México, Venezuela, Panama and Japan, she replaced the song for the Spanish version of it "Ven Conmigo (Solamente Tú)".

She also performed this version and "Pero Me Acuerdo de Ti" in Mexican comedy and variety show Otro Rollo.

[49] In 2000, Aguilera performed the Spanish version of the song "Ven Conmigo (Solamente Tú)" in the Telecinco's teen series Al salir de clase, where she also portrayed herself.

[53] In the Peruvian show Yo Soy contestant Katherine Vega covered the song personifying Aguilera.

[56] In 2023, "Ven Conmigo (Solamente Tú)" was featured in the sixth season of La Más Draga, performed by Cattriona Biñé.
