‘Baby on board’: Tennis legend Serena Williams shows off her bump in this new post

Serena Williams just only recently unveiled her baby bump and she already has a mama-to-be glow.

The 41-year-old tennis legend surprised fans with her reveal at the Met Gala.

On a post the tennis star put up on Instagram Wednesday, we can see that Williams’ second pregnancy (with husband, tech entrepreneur Alexis Ohanian) is going just swimmingly.

The Palm Beach resident took to Instagram to plug one of her new S by Serena dresses, which is not a maternity dress, but a pink, long sleeved frock festooned with flowers.

“Baby on board does not matter in the Sloane minidress,” she wrote in the caption of the design from her “strong, sexy and sophisticated” clothing brand.

We went looking for this $119 getup on the official website and were pleasantly surprised to learn that it’s more practical than it looks. The bottom half isn’t actually a skirt, but a skort, meaning a short is built in as well, and is technically, a romper. Nice.

Judging by the positive reception, the Sloane ought to sell out quickly:

“Crying how beautiful she looks now.”

“Baby is bumping cutely.”

“Wow, that’s a woman!”

The sibling in progress will join big sister Alexis Olympia, 6.
