Billionaire Bikini Babe Tamara Ecclestone Catches Some Rays In Miami

Tamara Ecclestone's body is all ready for summer.

The Formula 1 heiress, 28, showed off a tan, toned physique as she rested at Miami Beach's Casa Tua with fiance Jay Rutland, 31, on Tuesday, and we've got the shots for you right here on RadarOnline.com.

Clad in sunglasses and steaming things up in a snakeskin bikini, the socialite showed off an ample bust and carved abs as she enjoyed the sun on the pre-spring day, lazying away the day nibbling pizza, smoking cigarettes and canoodling with Jay, an ex-stockbroker.

The couple is slated to wed this summer in France, and Jennifer Lopez, Lionel Richie and Calvin Harris have been inked to entertain at the gig.
