The singer, who is returning to host The Voice for its upcoming 10th season, is also set to host a campaign fundraiser for Clinton at her Beverly Hills home on Nov. 4.
Aguilera, who is holding the event with her producer fiancé, Matthew Rutler, is pulling out all the stops for the Democratic hopeful – even planning a special performance in her honor, according to an invitation to the event obtained by PEOPLE.
This won’t be the first time the singer and the politician have crossed paths. When Aguilera was honored for her work as a UN World Food Programme Ambassador at an event in 2012, the two posed together for a photo, in which Clinton appeared to be staring at the singer’s cleavage.
Aguilera talked about the encounter during an appearance on The Ellen DeGeneres Show, saying, “That looks like it was Photoshopped but it’s not. It was a real moment.”
“She’s such a force in a room,” she added of Clinton. “She’s got that star charisma and everything about her. I couldn’t take my eyes off her, either, so it was mutual.”
As the two prepare to show off their mutual admiration for each other once more, we can’t help but wonder whether Clinton will sing alongside Aguilera. After all, she totally nailed her recent duet with Kate McKinnon on Saturday Night Live.
