Serena Williams and her husband Alexis Ohanian shared the news of their second pregnancy with their 5-year-old daughter, Olympia, on the day of the Met Gala. They were worried she might accidentally reveal the secret…but she was super excited at the news! Before apparently she had just thought that “getting fat.”

For the big reveal, the couple sat Olympia down and told her that Serena is not, in fact, getting fat – there’s a baby on the way! Olympia’s reaction was priceless as she exclaimed, “Are you kidding me?” and expressed her excitement. Olympia ran off screaming with joy, and even tumbled into the ground in her excitement, but reassured everyone that she was okay.
