Serena Williams has given birth to her second daughter! The tennis pro announced the arrival of her new baby, Adira River, via social media on Tuesday. The Olympian made the first reveal with a creative announcement video on her TikTok account. The clip starts with Williams’ husband Alexis Ohanian seated at a table on his laptop. Williams comes into the frame and joins him at the table. Ohanian kisses her forehead and embraces her as she sits down. The couple’s 5-year-old daughter Olympia joins the video and jumps into her mother’s arms. Williams then signals that she will “be back in one minute.” She then returns with their new bundle of joy. The family embraces each other and showers the infant with love as the video fades to show a collage of pictures featuring them as a new family of four. “Welcome my beautiful angel,” she captioned the clip while using the Bazzi’s appropriately named song “Beautiful” as the soundtrack. @serena Welcome my beautiful angel ♬ original sound –...
