"They (the contestants) were so excited. We went on a private jet to Las Vegas and they had never been on a private plane. It was nice to really show them things they maybe never could do in their life. They were really appreciative and so sweet," Hilton said.

As for her own qualities as a friend, Hilton said she was loyal, good at keeping secrets, truthful and generous.

"I will always tell you the truth. If you ask me if I like your outfit, if I don't, I'll say I don't. I'm a lot of fun. I love showing my friends my world and enjoying life," she said.

Hilton starts filming a second series of the show, this time set in England, next month and expects her new "friends" to be very different.

"London is my favorite city in the world. I love their accents, their attitude. They are so real, they are not fake. I feel that everyone in LA wants to be famous but in London it's more about business."
