London, April 7 : Tennis ace Serena Williams gave onlookers an eyeful after her tiny bikini bottoms reportedly fade away from view after she bend over to board a jet ski on Miami beach.

The curvy player was snapped enjoying the sun as she swam and played with seaweed in a skimpy black bikini.

The former world number one was said to have had the uncomfortable wedgie as she was taking a break with her boyfriend, reports the Sun.

Miami  - Serena Williams held onto her top ranking with a crucial victory Wednesday over China's Li Na, 4-6, 7-6 (7-1), 6-2 to reach the semi-finals of the Miami Masters.

The top seed and three-time champion at Crandon Park must get to the final to be certain of remaining atop the WTA table. If she loses Thursday to the winner from her sister Venus or Czech Iveta Benesova, then Russian Dinara Safina steps up to the summit.

Miami  - Serena Williams played her first match in nearly a month to reach the third round of the Miami Masters 6-2, 6-3 over fellow-American Alexa Glatch on Saturday.

The world number one was back on court after completing her annual pout by skipping this month's other big event in Indian Wells, where she and her sister Venus claim racial discrimination due to crowd jeers nearly a decade ago.

The 2001 incident still burns brightly for the Williams pair, who have vowed never to return to the California desert despite losing hundreds thousands of dollars in various sanctions from the WTA.
