Serena Williams and Karlie Kloss debuted their baby bumps in the most glam way possible

There are pregnancy announcements and there are pregnancy announcements—and it’s safe to say both Serena Williams and Karlie Kloss fall into the latter category. At Monday night’s Met Gala, both women debuted baby bumps on the red carpet, and both women looked absolutely fabulous.

The tennis superstar, 41, is expecting her second baby with her Reddit co-founder husband Alexis Ohanian. The couple are already parents to 5-year-old daughter Olympia. Less than a year ago, Williams announced her retirement from professional tennis in order to “expand her family.”

Williams initially shared the happy news via Instagram, in a carousel of photos of her and Ohanian. In one photo, Williams is holding her baby bump.

The post included the caption: “Was so excited when Anna Wintour invited the 3 of us to the Met Gala.”

Model and entrepreneur Karlie Kloss and her husband Joshua Kushner are officially expecting their second child—the couple confirmed their exciting news immediately prior to arriving at the Met Gala.

Like Williams, Kloss showcased her bump in a gorgeous black gown. Kloss and Kushner are also parents to two-year-old Levi Joseph.

When ET asked Kloss why she chose the Met Gala to reveal the news she was expecting, she said, “This is the most important night in fashion, of course, and I’m honestly surprised I could keep it a secret this long.”

Congratulations to the two mamas on their joyful news! What a night to celebrate, too.
