The singer and her fiance Matthew Rutler opened up their family pad for the political event, with guests also including Muse frontman Matt Bellamy, music mogul Irving Azoff, singer Christina Milian, actress Ambyr Childers, and film producer Randall Emmett.

Aguilera was on double duty at the carnival-themed bash as she also performed her hit Beautiful for the party and teamed up with collaborators Great Big World for a rendition of their track Say Something.

Addressing her famous fans, former First Lady and Secretary of State Clinton said, "The forces against progress never quiet, so we have to fight harder than ever to keep moving our country forward and that isn't possible without your support."

The concert event, which was attended by 400 people, raised $1 million (£625,000) for Democrat Clinton's political campaign.

Aguilera and friends aren't the only stars throwing their support behind Clinton - Demi Lovato and John Legend performed at the politician's 68th birthday party in New York City last month (Oct15), while Jessica Alba, Kate Hudson, Sharon Stone and Lady Gaga have all also campaigned for Clinton.
