(Cover) - EN Star Style - Olivia Palermo claims she is too busy travelling to be able to work out.

The pretty celebrity rose to fame on popular reality show The City, where she impressed fashionistas with her elegant style choices.

The 25-year-old has a great figure yet says that she cant improve her features even further by going to the gym regularly, as work prevents her from doing so.

I travel so much that workouts dont exist for me. I also have a bad back, which prevents me from working out most of the time, she told Look magazine.

However, Olivia does occasionally make time to get energetic with hunky boyfriend Johannes Huebl. The pair especially enjoy taking each other on in a game of tennis.

When I can exercise, I go to Bikram yoga, spinning, or play tennis with Johannes, she explained.

Olivia has no special diet to ensure that she stays in shape. The slim star is certain that she gets her fast metabolism from her mother , and says having a model boyfriend helps her stay in shape.

No I dont watch what I eat, Im really lucky. My mom has good genes, which I inherited, and I also grew up with very good eating habits, she enthused. I can eat what I like but I know I cant eat sweets 24/7. Johannes is very healthy too we eat a lot of sushi and fish. (C) Cover Media
