Kathy Hilton and Nicky Hilton support Britney Spears

Kathy and Nicky Hilton are Team Britney.

The mother-daughter duo expressed their support for Britney Spears following her bombshell conservatorship hearing on Wednesday — in which Spears mentioned that she didn’t initially believe Paris Hilton’s claims of boarding school abuse.

“Such a sweet girl,” Kathy said of Spears on the “Watch What Happens Live with Andy Cohen” after-show Wednesday. “And a good girl.”

“You should know we believe her,” said Nicky, 37. “Free Britney!”

Kathy, 62, told Cohen that while she and Nicky didn’t get a chance to hear Spears’ statement to the court, they both know the 39-year-old “Toxic” songstress and only had nice things to say about her.

During Spears’ explosive hearing Wednesday about her conservatorship, the pop star said she didn’t initially believe Paris’ allegations against her boarding school, so she thought nobody would believe her.

“To be honest with you, the Paris Hilton story on what they did to her at that school, I didn’t believe any of it. I’m sorry … I’m an outsider and I’ll just be honest, I didn’t believe it and maybe I’m wrong and that’s why I didn’t want to say any of this to anybody to the public because I thought people would make fun of me or laugh at me and say, ‘She’s lying, she’s got everything, she’s Britney Spears.’ I’m not lying. I just want my life back.”

Paris, 40, and the “Circus” singer were friends and often spotted together in the early 2000s before Spears was placed under a conservatorship in 2008. Just this week, Paris shared an old photo of them for National Selfie Day and wrote that 15 years ago, they “invented the selfie.”

The pop star broke her silence on her longtime conservatorship during a virtual hearing, claiming that it was “abusive” while comparing her father, Jamie Spears, to a sex trafficker.

She also said she wants to get married and have another child, but her conservatorship does not allow for it.

“I have an [IUD] in my body right now that won’t let me have a baby and my conservators won’t let me go to the doctor to take it out,” she told the judge. “I feel ganged up on. I feel bullied and I feel left out and alone.

“All I want is to own my money and for this to end and for my boyfriend to be able to drive me in his f–king car.”

Meanwhile, Paris revealed last year that she was allegedly mentally, emotionally and physically abused while attending Utah’s Provo Canyon School.

“It was supposed to be a school, but [classes] were not the focus at all,” she said in her 2020 documentary, “This is Paris.” “From the moment I woke up until I went to bed, it was all day screaming in my face, yelling at me, continuous torture.”

“The staff would say terrible things,” she added. “They were constantly making me feel bad about myself and bully me. I think it was their goal to break us down. And they were physically abusive, hitting and strangling us. They wanted to instill fear in the kids so we’d be too scared to disobey them.”
