The actress was spotted out Wednesday night at a Clinton presidential fundraiser in Beverly Hills, California, after several bombshell claims from Leah Remini surfaced over the past few days about Katie's former marriage to Tom Cruise while in the church of Scientology.
An attendee at the fundraiser tells ET that the party took place at Christina Aguilera's home in a gated community with heavy security. There was an open bar, and Christina performed her songs, “Say Something” and “Beautiful,” at the event.
Katie waited in a private room to meet Hillary, where a small group of people were able to take professional photos with the presidential hopeful.
It's been a long week for Katie, who has been the center of Leah's press tour for her book, Troublemaker: Surviving Hollywood and Scientology, which makes a lot of shocking claims about Katie, Tom, and Leah's time in the church.
During an interview that aired last Friday on ABC's 20/20, Leah talked about an alleged incident between her and the formerly married couple that got the King of Queens actress in trouble with church leadership.
Leah got emotional after hearing Katie's statement, prompting her to open up further about what she says they experienced in the church.
"It makes me emotional because, at the time, Katie and this particular crew were writing reports, it caused me a lot of time and pain in my family, being 'reprogrammed,'" she said,while appearing on Monday's Good Morning America. "So, at the time, I was fighting with her -- I guess for the lack of the better word -- within the Church, and now I know really what she was going through."
The Church of Scientology released a statement to ET regarding Remini's recent claims in both her book and recent interviews. The statement reads: "It comes as no surprise that someone as self-absorbed as Leah Remini with an insatiable craving for attention would exploit her former faith as a publicity stunt by rewriting her history with it, including omitting that she was participating in a program to remain a Scientologist by her own choice, as she was on the verge of being expelled for her ethical lapses."
