Olivia Wilde has broken her silence after giving birth to son Otis Alexander Sudeikis. The actress took to Twitter to joke about having a newborn son.

She first posted the first photo of her first child with fiancé Jason Sudeikis, writing, “Ladies and gentlemen, Otis Alexander Sudeikis has LEFT the building! (I'm the building).”

She then joked, “Having an infant son alerts me to the fact that every man, at one point, has peed on his own face. #awesome.”

As we reported, Wilde, 30, gave birth to Otis on Wednesday. The couple announced they were having a baby back in October, and they announced their engagement back in January 2013. They started dating in November 2011.

Wilde recently told Lucky Magazine that she wore her baby bump as a “badge of pride.” She also gushed about finding peace in being pregnant, “Pregnancy does shed away all of the bulls--t. It gives you more empathy because you look at everyone and you think, You were a baby!” It also, she says, has bonded her with other mothers. “Pregnancy brings you into this sort of commune—you feel connected to women in a way that you never have.”
