Christina Aguilera's 10 Best Collaborations

New Year, New Music! Christina Aguilera surprised fans on New Year's Day 2014 when she helped fellow diva, Lady Gaga, drop the newest version of the song "Do What U Want." Queen Xtina is the reigning champion of collaborations, boasting duets with everyone from Maroon 5 to Ricky Martin to Alejandro Fernandez. Luckily for you, we've sifted through her impressive repertoire and compiled her 10 best collaborations. Take a listen: 

1. "Do What U Want" with Lady Gaga

A week after performing together on the season finale of The VoiceLady Gaga and Christina Aguilera released a studio mix of "Do What U Want." Lady Gaga swapped out R. Kelly and Rick Ross (who appear in the original version) for a female-empowerment version with Aguilera. We can't stop listening to the catchy beat! 

2. "Feel This Moment" with Pitbull

"Feel This Moment" was the ultimate party jam of the summer of 2013 -- and for good reason. Pitbull and Xtina sang about the importance of living fast and hard. 

3. "Moves Like Jagger" with Maroon 5

Ah, the song that was stuck in everyone's head for the entirety of 2011. The Voice co-judges collaborated on the hot track "Moves Like Jagger" -- a song that hit #1 on the Billboard Music Charts and became the unofficial song of the year. 

4. "Lady Marmalade" with Lil' Kim, Mya, & Pink

Four fierce mujeres -- Christina, Pink, Mya, and Lil' Kim -- teamed up to remake the classic Patty Labelle hit "Lady Marmalade." The sexed up Christina version accompanied the romantic jukebox comedy Moulin Rouge! More importantly, it taught a generation of high school girls how to say "Do you want to go to bed with me?" in French. 

5. "Nobody Wants To Be Lonely" with Ricky Martin

Admit it: you had completely forgotten about this song. You're welcome for reintroducing you to a young Ricky Martin.

6. "Car Wash" with Missy Elliott

Queen Xtina took on the classic hit "Car Wash" for the soundtrack to Shark Tale. Missy Elliott and Christina Aguilera updated the ubiquitous disco song with a pop feel, and created a hit single that sold over 1.5 million copies. 

7. "Say Something" with a Great Big World

Christina Aguilera released this hauntingly beautiful ballad with A Great Big World late in 2013. The moving song is emblematic of Christina's new mission to only take on projects that projects that represent the "here and now" in her life. 

8. "Hoy Tengo Ganas De Ti" with Alejandro Fernandez

The Latina songstress teamed up with famous Mexican crooner Alejandro Fernandez for the sultry track "Hoy Tengo Ganas De Ti." Christina Aguilera stripped down to a slinky pair of black lingerie for the equally sexy music video. 

9. "Baby It's Cold Outside" with CeeLo Green

This Christmas classic is perfect year-round, especially when CeeLo Green and Christina Aguilera are the ones lending their powerhouse vocals to the jingle. This collaboration quickly became go-to holiday listening for us. 

10. "Can't Hold Us Down" with Lil' Kim

Christina teamed up with Lil' Kim once again for the feminist jam "Can't Hold Us Down." The song, aside from being one of the catchiest hits of the early 2000s, was among the first songs to address gender inequality and double-standards in society.
