Serena Williams’ daughter Olympia loves being a big sister! In a tik Tok video uploaded by the Tennis star, the six-year-old can be seen showering love on her baby sister, Adira River.

“Olympia is obsessed with being a big sis. She’s always pinching Adira’s cheeks,” Serena captioned the heartwarming moment.

During the CFDA Fashion Awards in New York City on November 6, Williams opened up about how Olympia is adjusting to becoming a big sister. Speaking to Entertainment Tonight, the 42-year-old tennis icon expressed, “She’s navigating it. She loves it,” the tennis pro told Entertainment Tonight. “Adira’s, like, a tiny little baby, so Olympia just calls her her little sis.”

Williams, who shares the joys of motherhood with husband Alexis Ohanian, revealed that Olympia had fervently “prayed for a sister. She’s been happy about how everything’s worked out.”

Before the arrival of Adira in August, Williams candidly admitted, “I was worried. I was like, ‘OK, I don’t know if I can like anyone as much as I love Olympia.’ I was really nervous about that. But I feel like it all worked out.”

The CFDA Fashion Awards provided Serena Williams with an opportunity to step out for a well-deserved “mom’s night out.” The mom of two graced the event in a stunning black sequin dress designed by CFDA Chairman Thom Browne, complemented by exquisite David Yurman jewelry.

Adding to the glamour of the evening, Serena Williams was honored with the prestigious Fashion Icon award at the ceremony. Reflecting on her lifelong relationship with fashion, Williams shared with CFDA, “Ever since I was a little girl, I’ve used fashion as an outlet to express myself — fashion gave me the confidence to step on the court and own who I was, and where I knew I was going.”
