During the interview, Hilton, in toned-down lace, spoke softly as she sat across from King.
"I've been through a lot," said Hilton, her blond hair cascading across her forehead. "And it was a pretty traumatic experience, something that I really have grown from."
She added that going to jail was the last thing she expected when Superior Court Judge Michael T. Sauer ordered her to his court in May for violating probation in an alcohol-related reckless driving case.
"I was walking in there assuming I was just going to get community service," Hilton said. "That's what my lawyer said at the time. So when he sentenced me to that much time in jail it was shocking, because that doesn't happen, ever.
"It wasn't for DUI, it was for suspended license," said Hilton.
The heiress revealed that her red carpet visit to the MTV Movie Awards the night she entered jail in early June was a ruse to throw off the press.
"Actually, I was playing a trick on everyone," she said. "Because outside my house, outside the Lynwood facility, there were paparazzi, I heard, from all around the world. So I thought, if I went to the MTV Awards, snuck out during the show, I could get there unnoticed. And that's what we did. No one even saw me going in... I don't want to cause a whole media circus going in."
She described Spears as "sweet" and a "good mom," who "loves her children."
Hilton is concerned for Richie, who is now facing the possibility of serving time for a DUI. "She's like my sister," said Hilton. "I love her so much and I don't want anything bad to happen to her."
She said she wishes only the best for Lohan, who is currently in rehab, and agrees that she's talented. Asked how well she knows the young actress, Hilton said simply: "I know her."
A few minutes later, King asked whether Lohan had any friends in rehab, and Hilton said "no."
