Erika Christensen just announced that she is pregnant with baby number two, and then accidentally revealed the gender.

The former Parenthood star was attending the Max Mara Celebration for another actress, Alexandra Shipp. As she talked to reporters about her pregnancy, she specifically stated that she wanted to keep the gender under wraps.

But pregnancy brain is real.

Christensen, clearly caught up in the moment, was describing a shirt that her mother bought for her daughter, Shane Maness, who is about to turn 2. The shirt has the words "Big sister" written across its front, and Christensen was so caught up in telling her story that she said, "Hopefully the little one will learn a lot from her sister".

Oops.

Christensen quickly laughed her mistake off and quipped, "Oh, well, there you go."

The Swim Fan actress also recently posted an incredible photo of herself and her sweet baby bump on Instagram, doing "acro-yoga" on the beach. The ocean created a blue background behind her, and Christensen's daughter appears to be standing beside her and her yoga partner, totally unbothered by the pose.

The actress and her husband, Cole Maness, were married on Septemeber 5th, 2015.  The wedding took place outdoors and was a small ceremony that included only family and close friends. Erika wore a gorgeous white gown, that was split up the front and made from a crochet-like fabric. She wore her hair up in a simple, elegant bun and carried a beautiful bouquet of pink and white flowers, that were accented with greenery.

Maness, the father of both of Christensen's little girls, is a cyclist who is known for his mustache. He has been vocal about his love for bicycling and outdoor activities through interviews and posts, but he is especially keen on one subject: his wife. He and Christensen spent the better part of their early years together on their bikes and he posts about his beautiful beau regularly on his Instagram.

Christensen, 35, has not officially released her due date yet. But the actress has called herself pregnant "AF", so she likely well into her second trimester.

Congrats to the Christensen/Maness family on their pregnancy! We cannot wait to see photos of the new baby when she arrives. And thanks especially to Erika, for giving us all a heads up on the gender!

Even if it was completely an accident.
