Just in time for summer, who among Hollywood's young celebrities have the body to rock a bikini?

They have the fame and the fortune but the downside of it all is they never have enough privacy to do what they want to do or wear what they want to wear without being on the headlines the next day. Whether they're just walking down the street or enjoying a family day by the beach, a photographer is just around the corner. But thanks to them, people get to see their favorite celebs wander around the beach in their teeny tiny bikinis.

It's not an easy job to maintain their sexy figures. Other stars like Miley Cyrus have once dedicated a lot of time doing pilates and stuck with her gluten-free diet. High School Musical star Vanessa Hudgens was always spotted in and out of gyms.

In the past, Kim Kardashian admitted that she lost ten pounds before she went on a vacation with her family in the Dominican Republic. She also said that she did intense workout and had a gluten, dairy and sugar free diet.

Rihanna who is also known for her rocking body said that swimming is one of her ways to exercise. The singer admitted that although she wants to be toned, she didn't want to lose her curves.

While some celebrities put in a lot of effort to be bikini ready, some are just blessed with perfect genes. Say for instance Selena Gomez and Nina Dobrev, they both rarely go to the gym or do workouts but still manage to look smoking hot in bikinis.
