The 29-year-old heiress is determined to slim her already-slender body down further in time for summer. She has been going to the gym every day and banned herself from consuming any of her favourite calorific burgers.

"I`ve been really working out. I`m not eating fast food anymore," Paris told UsMagazine.com at Victoria`s Secret What Is Sexy? party in West Hollywood on Tuesday. "No more McDonalds, In-N-Out done. I?m getting my bikini body, so I`m about that."

Paris has made no secret of her love of hamburgers in the past, even scoffing one on TV for a fast food chain commercial on 2009.

Paris flew from Los Angeles to Cannes last night on a private jet. She is planning to spend most of her summer in France and neighbouring Monaco, soaking up the sun on a luxury yacht.

"I`m just going to be on a yacht. Summer must have? A yacht," the blonde beauty said. "I`m going to St. Tropez, Monaco. I`ll be working as well, but a lot of relaxing."
