Put it in the baby books.

Fans on Cameo have requested that legendary Mets radio broadcaster Howie Rose reveal whether they are having a boy or a girl.

“There’s a lot of ‘Here’s our gender reveal, would you announce to everybody what we’re having,'” Rose told The Post of his account on Cameo, where a celebrity records personalized video messages for a fee. “It’s fun.”

Other requests have included “introducing the bride and groom at their wedding or a bar mitzvah or something like that,” said Rose, 69, whose talking bobblehead is being handed out at CitiField on May 31.

Perfect timing, because on June 3 Rose will join players Howard Johnson and Al Leiter and fellow broadcaster Gary Cohen in being inducted into the Mets Hall of Fame at Citi Field.

Twitter users have called for Rose to be honored with the polyresin replica for years.

“By popular demand, absolutely. They’re banging down the doors to get a Howie Rose bobblehead,” Rose said of the doll, which utters his famous catchphrase “Put it in the books.”

Rose was initially opposed to joining social media, and didn’t create a Twitter account until 2020.

“I didn’t trust myself because I know me and I figure I’ll have dinner and … maybe a couple of glasses of wine, and then I’ll think, ‘You know what? Yeah, I could say this.’”

However, once the pandemic hit, he felt disconnected from his listeners and decided to post his first tweet — not realizing he did it on the same date, April 11, that the Mets played their first game.

“It was pure irony … I just realized it later that night and said, ‘Oh, this is spooky,'” he remembered.

The Brooklyn native who grew up in Bayside, Queens, remembers when he would attend baseball games at Shea Stadium when general admission was just $1.30 and the bus ride there 15 or 20 cents.

“If I could scrounge two bucks off of my parents, which was a challenge … I still had money left over to buy a scorecard and maybe a hot dog,” he recalled.

Now, his stadium food of choice is sushi from Daruma of Tokyo.

“To me, sushi is the new pizza,” he said. “And whenever I get a chance, I try to have that before a game.”

He admitted to shedding a tear on air, when the team won the National League pennant in 2015.

“As I was finishing my final call, if you listen very carefully … I said, ‘They’re going to the World Series’ and you could hear my voice crack just a little bit,” he explained. “Because it was sort of your whole career, your ambitions and your dreams being crystallized in that moment.”

Earlier this year, he revealed his battle with bladder cancer, and has received an outpouring of support.

“Since then, I’ve had a number of people get in touch with me whom I’ve had conversations, trying to help them through something similar that they’re going through … And it’s been somewhat cathartic,” he said.

Rose has no plans of retiring anytime soon and is hoping he can one day announce a World Series win for his beloved team.

“I’m hoping that happens this year,” he said. “And if not, next year and God willing and health willing, I’ll hang on as long as I can to have a chance to make that call.”
