Socialite Paris Hilton has travelled to Mexico City last week. Besides shopping and seeing pyramids, the beautifull heiress had some business to attend to: promoting ther new film, her namesake perfume and a book, published last year.

"You know, I love working. It's fun," muchmusic.com quoted Paris telling reporters. " I love making my own money. I'm doing jobs I love to do so it's great. I'm getting paid to have fun. I think it's important for me to do it on my own. I don't take anything from my family and it's a lot of work but I love it."

After spending two days at the Caribbean resort in Cancun Paris went to Mexico where she missed an interview with "Otro Rollo," Mexico's version of 'The Late Show,' by choosing to party with her sister, Nicky, instead, claimed one of the locals.

The “The Simple Life” star appears in House of Wax,” which isis set to hit the US cinemas in May 6. Elisha Cuthbert and Chad Michael Murray are to appear on the screen in the 1953 Vincent Price horror movie remake alongside Paris.

As for her new fragrance, the famous beauty said it smells like flowers.

"Confessions of an Heiress: A Tongue-in-Chic Peek Behind the Pose" is the book of the 24-year-old heiress, who wants to try her hand at everything, even at jewelery, accessory and clothing design.
