While the parents are thrilled about the new addition to their family, they did admit it was a surprise.

"It's a Hail Mary!" the 43-year-old actress said, getting emotional. "I'm so happy — we're so blessed. We were so shocked, but we're thrilled."

She joked to PEOPLE that the pregnancy is "what happens when I go visit my husband on the movie set."

While she is used to having little ones at home, she did share that her age is something she considered when she got the news.

"Being 43 is a little worrisome," the high-energy mom revealed, "cause I'm like 'Okay, you are going to be 90!' But then Mick Jagger [is having a baby at 72] so we're like okay, we feel good about ourselves."
