There’s no denying that Serena Williams maintains her fantastic physique, thanks to her rigorous tennis regimen.

Over the weekend, Serena showcased her figure in a revealing black swimsuit as she partied with friends at Encore Beach Club at Wynn in Las Vegas.

During the poolside bash, the 34-year-old tennis star had a starstruck moment when she met Brazilian soccer player Neymar and posted a photo on Instagram to commemorate it.

“Always be ready for summer. You never know when @neymarjr will show up,” she captioned the photo.

Serena wore her black hair in soft waves and accessorized with a nameplate necklace.

Neymar, 24, was spotted shirtless, sporting a pair of patterned purple swim trunks.

The fun encounter was also captured in a video, showing the pair in high spirits, blowing kisses.

Serena was in Las Vegas for a girls’ weekend to celebrate her friend Ciara’s bachelorette party, along with singer Kelly Rowland.

Other attendees included Ciara’s makeup artist Yolonda Frederick and hairstylist Kiyah Wright, among others.

The 30-year-old “Goodies” singer is gearing up to marry NFL player Russell Wilson.

The group enjoyed the weekend poolside in a private cabana, sharing playful Snapchats and videos of their dance moves.

Back in her hotel room, Serena also posted a few cheeky clips of herself twerking and admiring her reflection in the mirror.

The tennis champ is currently relishing some well-earned downtime after the French Open.
