Christina Aguilera played host to a Hillary Clinton fundraiser at her home Wednesday night, which was attended by the likes of Katie Holmes, Matt Bellamy, Christina Milian and Irving Azoff.

In all, TMZ reports the deep pocketed soiree was attended by about 400 people, all of whom paid between $500 and $10,000 to be on hand.

Word is Aguilera opted for mellow tunes throughout the event, actually singing such hits as "Beautiful" and "Say Something."

The Aguilera event comes just days after Katy Perry joined Clinton in performing at a political event in Iowa. In fact, more and more it appears that Clinton has won over the Hollywood crowd.

Not long ago, Kim Kardashian and Kanye West joined an overflow crowd at the home of Justin Bieber's manager Scooter Braun for a $2,700 person fundraiser. During the event, Clinton posed for a selfie with both West and Kardashian as momager Kris Jenner looked on.

Prior to that, NBA legend and business mogul Magic Johnson let it be known he is all in for Hillary, tweeting that he and wife Cookie are thrilled about Clinton's democratic run for the Oval Office. Johnson also supported Clinton during her initial run for the White House in 2008.

"I feel @HillaryClinton will be a great President for the American people and she will make sure that everyone has a voice," he added in his post. "@HillaryClinton will fight for the poor, middle class and embrace young people."

A recent CNN poll found Clinton now leading Democratic rival and Vermont Senator Bernie Sanders by a whopping 41 points in the critical, early voting state of Iowa.

Overall, the nationally conducted Monmouth University poll found Clinton garnering 65 percent of the vote to just 24 percent for Sanders and five percent for former Maryland Gov. Martin O'Malley.
