She has been showing off a tinier waistline lately on Instagram.

And on Sunday Paris Hilton explained how she has slimmed down so quickly.

'I stopped drinking soda about a year ago,' the 34-year-old perfume mogul and DJ told Daily Mail exclusively. 'It just shrank my midsection almost overnight.'

The Come Alive singer added that she chose to leave bubbly drinks out of her diet because she is trying for a healthier lifestyle.

'I wanted to drink more water and also I just got tired of it,' the blonde beauty said.

'I used to like Coca-Cola, that was my top soda, because I liked the sweet flavor. I never drank Diet Coke because I didn't like the way it tasted.'

She also said she is drinking her vegetables.

'I like green smoothies, they taste good and they make me feel more energetic,' she said.

'I also like regular juices. I get a lot more vitamins these days, more fruits too, more vegetables, more protein, more salads.'

This comes after the Beverly Hills native cut fast food out of her life. In July she told Daily Mail she lost weight immediately by saying no to quick burgers and fries.

'I lost about five pounds just from staying away from the Drive-Thrus,' the Simple Life star said.

'I can feel the difference especially when I'm in a bathing suit.'

A fast food habit started when she was very young.

'I used to eat that way, but I decided to change things this year,' she said. 'Now I don't do that. There are times when I will stop at a Carl's Jr, but I will maybe get a turkey burger or something healthier instead of a cheeseburger and fries. I am more careful now.'

The former Guess model added she is not doing is hitting the gym.

'I have never been a gym person, it's not me,' Hilton told Daily Mail at the time.

'I don't think people expect to hear this, but I grew up a tomboy. I would always play ice hockey, go skiing when I could. I would surf, ride bikes, swim. I love to work out outside. I have always been very active.'

But she does admit a new love for Pilates.

'It's a great way to exercise because you use so many muscles and get a really good workout,' the Stars Are Blind singer told MailOnline.

'I use the machines, not mat Pilates, and it just works for me.'

On Wednesday - the same day she launched her 18th fragrance in New York City - Hilton talked to Daily Mail about bullying online.

'I don't put up with bullying,' she said. 'I just don't let it in my life. I focus on the positive instead. And I use humor to deflect negative comments.'

Hilton is known for her quick and clever comments to her detractors.

When DJ Deadmau5 put down her skills as a celebrity DJ in October, she smartly responded on Twitter.

'I find it hilarious when others try to badmouth me in order to get attention. Sorry that I'm #Killingit while doing what I love & live for,' the star wrote.

Her DJ track record speaks for herself - she is one of the top talents in the business with gigs in Hong Kong, London and Ibiza.

Hilton is also humorous when it comes to her Instagram posts. On March 4 the Stars Are Blind singer shared, 'Dear Haters, I have so much more for you to be mad at. Just be patient.'

Days before her message read, 'Good Vibes Only.'

'There are always haters in life, especially if you're successful,' the daughter of Kathy and Rick Hilton said.

Dealing with the downsides: 'There are always haters in life, especially if you're successful,' the daughter of Kathy and Rick Hilton said

'I don't like bad energy. So I focus on doing well, on things that are positive. I am proud of my accomplishments and what I have achieved. So I think about that and all the good I can do.'

Humor can play a big part in dealing with people who want to bully.

'If you joke about it, then you are sending out the message that you don't take the hating seriously and you don't care,' added the hotel mogul.

The House Of Wax actress also had advice for young people dealing with bullying: 'You can't let bullying get to you. It's not your problem it's theirs. The haters should be focusing on themselves and not you. You need to just not pay attention to it. Those people need to stop the bad energy.'

The blonde bombshell wore a shimmery silver dress and a white cardigan for her appearance in Manhattan to welcome her Paris Hilton Limited Anniversary Edition eau de parfum spray that comes in a rhinestone-encrusted bottle.

The sweet smell of success: Hilton's fragrance empire is worth $2 billion, according to Yahoo Beauty

'While many experts feel the celebrity fragrance bubble has burst, Hilton, who just launched her last offering in November, has sold 40 million bottles and $2 billion worth of perfume over the past 10 years,' Yahoo Beauty reported on Wednesday.

'I love all my fragrances,' Paris told Daily Mail.

'I wear all of them too, I trade off. It depends on my mood. So I don't have a favorite. My personal style has grown over the years so the fragrances have grown too. I have matured and grown up.'

The niece of Kim and Kyle Richards added she is hands-on with her fragrance business.
