Paris Hilton discovers the meaning of life::

The blonde heiress Paris Hilton thinks it's great that she is one of three siblings and has been thinking about starting a family with her Las Vegas nightclub owner boyfriend Cy Waits.

She said: "I think having kids is the meaning of life and I really believe that.

"I definitely want to have a couple of kids when I do because being an only child is hard and I always loved growing up with a big family."

At the moment, Paris is spending a lot of time with Cy's seven-year-old daughter Shae and she regards the youngster as her new best friend.

In an interview with RadarOnline.com, she said: "Shae is such a sweet, beautiful little girl. She is so smart. Shae is Cy's daughter, and she is amazing and I love her so much.

"She is an animal lover like me. She is smart, she is very mature.

We love going to the pet store and playing with animals ... going to Circus Circus, going on rides and playing games. It's fun, it's like having a little best friend."

Paris recently vowed to curb her partying lifestyle and insists she now loves nothing more than quiet nights in with Cy and Shae.

She added: "We spend a couple of days every week in Las Vegas. We go back and forth to see her and when we are there it's completely different from when I used to go to Vegas.

"We cook dinner at home. We play with all the bunnies in the backyard. We do normal things like go to the movies, and relax and just get her ready for school.

"It's definitely a different pace but I'm really enjoying and loving it."
