Paris Hilton insists she has never been happier.
The hotel heiress - who turns 30 on Thursday (17.02.11) - says her career is going well, she's in a great relationship with Cy Waits and is fitter than ever because her nightclub manager boyfriend has become her personal trainer.
In an interview with heat magazine, she said: "Life is great at the moment! I have my new show, 'The World According To Paris', starting soon; things with my boyfriend are great; and now I have a new weekly workout, which I love.
"Me and Cy have been training together for the past three months. It's all new to me. I used to hate working out, but I started because it was something we could do together. I wanted to try something he enjoyed. He makes it fun for me.
"It's great, because I get to spend time with Cy and we're so happy together. We're either in the gym or playing tennis and are always laughing, so the time just flies. And now I've realized how important it is to look after my body."
Because of her new fitness regime, Paris now feels very confident with her toned body, and has come to appreciate that she must treat it with respect.
She said: "Getting fit has given me the energy I need to cope with my hectic life.
"I'm seeing lots of great changes! For the first time in my whole life, I feel really fit. I have lots more muscle tone all over my body. I've totally cut out fast food and sodas. Pretty much everything I eat now is organic."
