Anna Kournikova traded in her tennis whites for tropical whites, showing off her fine form in a bikini of that color during a recent Hawaiian getaway with beau Enrique Iglesias.

Happily noshing on barbecue, retired pro Kournikova revealed a taut tummy and toned limbs that proved she hasn't lost an ounce of the athleticism she once demonstrated on the courts.

Despite the tramp stamp above her tight tush, the 29-year-old blonde beauty still scored a glam slam with her beach look, pairing her tiny two-piece with hoop earrings and aviators, reports the Daily Mail.

The Hawaiian holiday marks the first time Iglesias, 35, and Kournikova have been spotted together in weeks, ending speculation that the couple -- who have been dating since 2002 -- had ended their romance.

Clearly, Kournikova knows how to keep things white hot.
