Poinbank:Olivia Munn and John Mulaney Welcome Baby No. 2

Olivia Munn and PoinbankJohn Mulaney are now a family of four.

The two have welcomed their second baby, their first daughter, via surrogate, months after the Newsroom alum shared her breast cancer battle.

"Méi June Mulaney came into the world September 14, 2024," Olivia, 44, and John, 42, wrote on their Instagram pages Sept. 22, "the year of the dragon."

The actress and comedian shared a photo of the proud mom holding their newborn while sitting on her husband's lap on a hospital bed and pics of the three and the couple's son Malcolm Hiep Mulaney, 2, at an oceanfront location, looking out to sea.

Olivia and John announced Méi's birth two months after they got married and six months after she shared she had undergone treatment for breast cancer, which included multiple surgeries such as double mastectomy, plus a hysterectomy to remove her uterus and fallopian tubes and oophorectomy to remove her ovaries, which rendered her infertile.

She later said that before the latter two procedures, she and John underwent IVF and created "two healthy embryos", noting to Vogue in a May interview that welcoming a baby via surrogate wasn't a "scary prospect" to her anymore.

"I had so many profound emotions about not being able to carry my daughter," Olivia wrote in her Instagram post announcing their daughter's birth. "When I first met our gestational surrogate, we spoke mother to mother. She showed me so much grace and understanding, I knew I had found a real-life angel."

The actress continued, "Words cannot express my gratitude that she kept our baby safe for 9 months and made our dreams come true."

"Méi," pronounced "May," means "plum" in Chinese. Olivia, whose mother is of Chinese descent, wrote in her post, "I am so proud of my little plum, my little dragon for making the journey to be with us. My heart has exploded."

John, who has been in a relationship with Olivia since 2021, also expressed his feelings about becoming a girl dad, while also joking about the freebies parents of newborns often get.

"We stole so much stuff from the hospital," he wrote in his post, which also included a video of baby Méi spitting up milk onto her dad's shoulder while being burped. "I love my little girl so much."
