As far as Christina Aguilera's concerned: ain't no other man can stand up next to [Hillary Clinton].

Last night, exactly 10 years after the release of Xtina's big band-inspired hit "Ain't No Other Man," the singer performed Back to Basics' lead single at She's With Us, a Los Angeles fundraising event in honor of Hillary Clinton. And the song seems to have provided a bit of good luck, as the Associated Press has since reported Clinton has secured enough delegates to clinch the Democratic nomination for President of the United States — she's the first woman to ever get the distinction from a major party.

In the clip above, and with a brand new red hairdo, Xtina belts through her 2006 hit in front of a crowd that included the likes of John Legend, Stevie Wonder and Ricky Martin, who also performed, according to People"Ain't No Other Man" which won the Grammy for Best Female Pop Vocal Performance in 2007, reached No. 6 on the Billboard Hot 100 and has been certified platinum.

And while there seemed to be much to celebrate for Clinton, she remained focused on today's (June 7) primary elections in California, Montana, New Mexico, North Dakota, South Dakota and New Jersey.

Watch Xtina perform her decade-old hit above, and tell us where you think it ranks among her catalog of hits.
