Serena Williams & family release their inner Swifties at Eras Tour in Miami

Serena Williams may be known for her legendary tennis career, but recently, she stepped into the spotlight as a devoted Taylor Swift fan, sharing the experience with her two daughters.

Over the weekend, Williams and her daughters, Adira River, 14 months, and Alexis Olympia, seven, attended Swift's highly anticipated concert at Hard Rock Stadium in Miami.

Serena Williams gave fans a rare glimpse of her family preparing for the concert, posting a series of photos on Instagram.

"This is us... getting ready for @taylorswift," Williams captioned the post.

In the snaps, Serena looked chic in a black mini-dress paired with black sneakers, carrying Adira, who wore a playful outfit of a white T-shirt and denim shorts.

Olympia channeled her inner Swiftie, dressed in a sparkly ensemble inspired by Swift's Lover tour, complete with silver boots and pastel pink pants.

While Olympia has long been a fan of Swift, Serena hinted that Adira, too, might be catching the Swiftie bug.

"My daughter just turned 7. She's not into princesses, she's into Taylor Swift," Serena shared in a previous interview.

Now, it appears the love for the singer is spreading to the youngest member of the family.

Serena's excitement for the concert was evident, especially in a video she posted showing her jumping up and down to the beat as Swift performed.

Captioning the post, she wrote, "Oh, just a casual Swiftie over here (maybe not so casual) @taylorswift #miami #erastour."

This isn't the first time Williams has openly expressed her admiration for Swift.

Over the years, the 23-time Grand Slam champion has shared her love for Swift's music, often mentioning how much it resonates with her.

Now, as Swift's fanbase continues to grow, it seems the Williams household is fully on board, with husband Alexis Ohanian recently admitting he's also become a fan.

"I'm a Swiftie now. Amazing experience," Ohanian shared after attending a Swift concert with the family earlier this year.
