Whitney Port rocks a unique one-shoulder bikini

Whitney Port may have given her budding fashion designing career a boost when she was spotted wearing a unique one-shoulder bikini in Hawaii yesterday. The 25-year-old rocked her black one-shoulder two piece with pink flowers at the Waikiki Edition Hotel.　

Whitney looked extremely comfortable in her original look as she walked solo on the beach before settling down for a snack, along with a kiss and a cuddle with her boyfriend Ben Nemtin.

And it wasn't just a bikini strap that the reality star let down that day. Whitney usually tries to maintain a strict no-carb diet, but she finally let her guard down and nibbled on a slice of pizza.

Less than 24 hours earlier, Whitney　 was seen snacking on just an apple but couldn't resist the greasy cheesy treat that she happily shared with Ben.　Whitney also indulged in a second guilty pleasure - reading the latest editions of　 People and In Touch magazines.

Following her carb-fest though, Whitney made sure to eat another apple before she and Ben, 26, took part in a major make-out session, perhaps to burn off those excess pizza calories. Nemtin is an actor and producer from the MTV reality series The Buried Life.

But Whitney can certainly afford to pile up her plate. Her bikini-clad pictures revealed　 her jutting hip bones, and pin-thin legs.　There isn't an inch to pinch on Whitney's 5'10' frame which weighs in at a reported 115lbs.

And while her thinness has caused concern, the fledging fashion designer says she is 'happy' with her body now.Whitney claimed that she gained 'love handles' after leaving college and has since embarked on a strict diet and workout regime.

She tries to avoid carbs, sugar and fried foods and works out regularly with a personal trainer, takes long walks, plays basketball and bike rides. But obviously sneaking in the occasional pizza slice is allowed, especially if she's on a Hawaiian holiday.

The Los Angeles native once told US Weekly that she has 'never eaten pasta'.　Whitney is currently on vacation in Hawaii and joined numerous celebrities in the Aloha state to celebrate the opening of the new Marriott Waikiki 'Edition' Hotel. The trip to Hawaii comes as Whitney ponders her next move as she is uncertain over whether her reality show The City will continue.

'Good question - I don’t know!' the MTV reality star, 25, told UsMagazine.com

'Everything is so up in the air.'

Currently living in Los Angeles, Port said she will probably focus on expanding her collection Whitney Eve - on the West Coast.

'My family and my friends are out here, so it's where my heart is. But I will continue to do my line, which is really what I always wanted to do anyway.

Burning calories? Perhaps the kissing and cuddling can help reduce those pizza carbs

'The City is great and so much fun to do, and I'm able to share what I do with so many people, [but] it'll be OK.' In addition to her Whitney Eve collection (which just showed at New York’s Mercedes-Benz Fashion Week), she has launched a new affordable line, the Seamless Collection.

'I've made a separates collection with basically all these layering pieces, like leggings, bandeau bras and little Spandex numbers to wear under things.' Whitney has been dating Nemtin for the past seven months. Port gushed: 'He's wonderful.'
