Serena Williams dispelled pregnancy rumors over the weekend, without needing to say one word. The tennis champion showed off her impressive curves in a coral bikini while in Croatia -- and none of those curves included a baby bump.

Williams was rumored to be pregnant after appearing disoriented in a first-round doubles match with sister Venus at the Wimbledon Tennis Championships earlier this month. The No.1 seed, who also lost to Alize Cornet of France in the third round of the singles tournament, later said in a statement that she had a bug and it “just got the best of me.”

But tabloids claimed it was much more than a bug. German tabloid Bild said the 32-year-old is pregnant, and the symptoms that come with pregnancy caused her to become woozy during the match. “In London, word is that Serena was impregnated by her coach,” an insider said at the time.

While in Croatia, however, Williams displayed a taut stomach, showing off her waist in a number of revealing outfits.

Williams is dating her French coach, Patrick Mouratoglou. Speculation that the two were an item first began last September, after Williams was spotted in Paris with Mouratoglou with their hands in each other's pockets and embracing as they walked down the streets. The pair have since been seen together, mainly in Paris, where Williams has a second home.
