Paris Hilton has been "burned" by friends in the past.
The hotel heiress has launched her new MTV reality show called 'Paris Hilton's My New BFF' - which sees the star attempting to find herself a new Best Friend Forever (BFF) - but admits being a celebrity makes it difficult to forge relationships.
She said: "It is really hard because you're not really sure if people want to be friends with you for the right reasons or they just want to be famous.
"So it's hard to figure that out, but I can figure it out now. If you are burned a couple of times in life you definitely learn from your mistakes."
The 10-episode show sees the 27-year-old star whittle down a group of 19 potential pals until she finds her favourite.
Paris enjoyed making the programme as it gave her the chance to meet people from parts of America she would not normally visit, and insists she made some lifelong friends.
She said: "It was a lot of fun to do a show like this to meet people from all around America and outside of Hollywood. It's so different and such an amazing experience. I'm so excited that I get to re-live it and watch it this season.
"I really did make some true friends and even though I got to pick one, I made a lot of friends and we've been hanging out all summer long. Definitely my BFF that won the show is my BFF forever."
