On Wednesday, the fashion designer and her husband, Eric Johnson, welcomed their daughter, Birdie Mae Johnson.
So how are Simpson's kids feeling about their little sis? They couldn't be happier, according to a source.
"Max and Ace are so excited about the baby," a source tells E! News. "Seeing them with their new baby sister has made it all worth it."
