Kathy Hilton keeps explicit photos of herself locked in a bank vault

Kathy Hilton revealed she has explicit photos of herself locked away in a bank.

The reality star made the steamy confession during Tuesday’s episode of “The Real Housewives of Beverly Hills” after she was asked by her sister Kyle Richards whether she’s ever sexted her husband, Rick Hilton.

“We have a couple in the safe in the bank,” Kathy, 65, said, sharing that she’s never sent any racy pictures via text message.

“Caesars Palace in Las Vegas, they have those beds with the big mirror. Seriously, it’s so sexy,” she teased of the images.

Richards, 55, responded to the revelation in her confessional, joking, “Who puts their nude photos in a vault at the bank? I’m just picturing Kathy naked with, like, fuzzy socks and a hat on.”

Kathy isn’t shy about sharing how she keeps the romance alive with her husband of 45 years.

In January, the reality TV star revealed she and Rick, 69, have date night at The Cheesecake Factory once a week.

“He really likes the chicken. And then also the one that you dip with the sauce,” she told Page Six of her spouse’s go-to dishes, noting that “all their food is good.”

“It’s local, it’s right there and fresh and busy all the time,” the Bravolebrity who is a big fan of their meatloaf, added of the restaurant chain.

“Actually, you walk in there and there are people. We love that! We don’t want to sit in a restaurant with nobody in the room.”

The famous couple tied the knot in November 1979 and share four children: daughters Paris Hilton, 43, and Nicky Hilton, 41, and sons Barron Hilton, 35, and Conrad Hilton, 30.

In September, Kathy also revealed her secret for a long-lasting marriage, telling People she and her husband have not been “away from each other for two weeks” in all of their years of marriage.

“I don’t think you go to bed without saying, ‘I love you,’ and giving each other a kiss and never in a fight or anything,” the “RHOBH” star added.

“If you have had a disagreement, you always make up before you go to sleep and keep a little mystery and always keep it exciting and fun.”
