John Mulaney and Olivia Munn have welcomed their second child. The announcement comes just weeks after his ex-wife published a memoir.

The actress expressed gratitude for the gestational surrogate who carried their child after Munn revealed in March that she underwent a double mastectomy among other surgeries in the months following her breast cancer diagnosis.

Munn, who earlier this year revealed she had undergone a hysterectomy and was not able to carry a pregnancy, praised her surrogate in an Instagram announcement.
