BROLIN HAS GOT NEW FAM ROLLIN’

’Deadpool 2” actor Josh Brolin and wife Kathryn Boyd (above) are expecting their first child together.

The couple announced the pregnancy — a girl— in a pair of Instagram posts shared on their respective pages Tuesday morning.

“Something’s cookin,” the 30-year-old expectant mother and actress captioned in a shot of her baby bump. “Baby Girl Brolin on the way.”

Brolin, 50, spread the news via a similar snap of Boyd while on a hike.

“There’s a new sheriff in town,” wrote Brolin, “and she’s no bigger than a sweet potato.”

The girl will be Boyd’s first child and Brolin’s third. The actor, who earned an Oscar nomination for 2008’s “Milk,” has two adult children from his first marriage to Alice Adair. Brolin was also married to Diane Lane from 2004 to 2013. Boyd and Brolin wed in 2016.
