In an endearing video posted on her YouTube channel on Tuesday, tennis legend Serena Williams, 41, shared the moment she told her five-year-old daughter Olympia that she was going to be a big sister.
The athlete, who revealed her second pregnancy on the Met Gala red carpet earlier this month, titled the YouTube clip "Olympia's Surprise."
Serena began the video by showcasing a positive pregnancy test up close to the camera, her smile radiating with pure happiness.
In an amusing twist, she shared that Olympia had yet to be informed of her pregnancy, yet was perturbed by her mother's apparent weight gain and even called her 'fat'.
As the video unfolded, Serena's husband, Alexis Ohanian, 40, joined her to tell the delightful news to their little girl.
Dressed fashionably in a Gucci sweater and blazer, Serena presented the announcement in a relaxed, vlog-style chat.

"Olympia does not know right now that I am pregnant, but she did call me fat, and then she got really like stressed out," Serena informed her audience.
The tennis superstar then imitated her daughter's dismayed voice, "'Mommy, you're fat.'"
Despite her commitment to fitness, Serena took the comment in stride, admitting, "I tried not to take it personal, 'cause I'm like super into fitness, but I'm like, 'uhh, am I?'"
The scene transitioned to a wholesome family moment on the couch, with Olympia nestled between her parents in her floral pyjamas.
