Kathy Hilton says daughter Paris Hilton, 43, and longtime pal Nicole Richie, 42, are still like ‘two little kids’… as they reboot The Simple Life

Paris Hilton, 43, and Nicole Richie, 42, are businesswomen, reality TV stars, wives, mothers and socialites.

But when they get together, they act like little children, according to Paris’s 65-year-old mother, Kathy Hilton.

The Real Housewives of Beverly Hills star opened up about the close bond childhood friends share.

She said OurWeekly at the Ladies Who Longevity Lunch, which Kathy – who recently flew to Italy with daughter Nicky Hilton – organized.

“You know what’s great, when they get back together it’s like they’re still 12 years old,” she said.

“When they come together, they’re like two children,” she enthused.

Paris and Nicole showed the world their friendship in the 2003 reality TV show, in which the hotel heiress and daughter of music star Lionel Richie got to see how the other half lived – often to great amusement and awkwardness.

“For the first show, I put them both on the bed. I didn’t know where they were going,” Kathy explained to the outlet.

“I wasn’t here for this at all… and I was wrong. It was the funniest show.”

And the proud mum reviewed her daughter’s reality TV debut, calling it ‘iconic’.

‘It was without swearing, without fighting [and] it was really cute and fun and just silly and a lot like me,” Kathy added.

Last month, news broke that Paris and Nicole were planning to reboot The Simple Life, 21 years after it first aired.

The premise of the series has not yet been revealed, but sources within the production say that it will not be an exact copy of their previous series, nor will it have the same name.

Paris and Nicole have already sold their pitch to Peacock, after all scheduling issues were resolved, so they could work together again.

And Kathy is totally into the reboot, saying, “I think it’s going to be exciting. The two of them are a dynamic duo.”
