Katy Perry Bids $50,000 At Charity Auction For A Date With Orlando Bloom

Perry later spoke to Entertainment Tonight about her participation in the charity event -- and why it was so important to her.

"My pianist that is playing with me, he lost his house and we were on tour, and then he came home and he didn't have a home, so, it's been kind of intense and it's very personal," she said.

Perry also performed during the "One Love Malibu" concert at the King Gillette Ranch in Malibu earlier that day -- along with artists like Rita Ora, Natasha Bedingfield, and more. The singer advocated for her pianist when she entered the stage, revealing that she was primarily there to help him, and anyone else affected by the fires.

Robin Thicke, who lost his own home in the Woolsey Fire, also took to the stage to perform. He shared that two of his bandmates had lost their homes as well.

"We have an opportunity to grow together now," she said, according to the Hollywood Reporter.

Demi Moore, Whitney Cummings, and Dick Van Dyke also gave touching speeches during the concert. Each of them thanked the audience for coming together with love and support for the Malibu community.

Overall, close to $1 million was raised on Sunday. Donations are still being accepted on the Malibu Foundation's website.
