She’s one of the top athletes in the world.

And Serena Williams proved to be a sports fanatic as she shared several videos taking in the sights and sounds of the Monaco Grand Prix on Sunday morning.

The 39-year-old professional tennis player cut a casual figure as she enjoyed a private boat ride before heading back to shore and promptly attending a Formula One racing event.

Serena looked completely at ease as she shared a breathtaking view while spending time on a private boat.

Williams wore a black sleeveless bodysuit and stayed warm with a classic blue jean jacket during her outing.

She paired her tight tank top with a brown plaid pencil skirt and wore her brown hair in natural curls.

She notably wore a black facial covering with her brand’s S by Serena logo to keep herself protected from COVID-19 while spending time around other people.

In the pit: The tennis legend was afforded some up close and personal access as she gave her followers a look at the action in the pit

At one point, she made it onto a racetrack before the start of an event and spent time walking around the area and checking out the teams preparing to send their drivers off.

The Olympian also sent a shout-out to her ‘best friend,’ Lewis Hamilton, who took part in the day’s races.

She then spent time in front of Aston Martin’s team’s garage and gave her 13.1 million followers a closer look into the pre-event preparations that were being taken.

Once she made it back to the boxes, Williams reconnected with her husband, Alexis Ohanian, who appeared enthusiastic about the upcoming races.

She also shared shots of herself relaxing on a rail above a racetrack and wearing a pair of noise-muffling headphones while enjoying the event.

The tennis champion’s two videos from the race showed a pair of cars pulling into their respective maintenance areas while teams of technicians checked on the vehicles.
