Kristin Cavallari, Jay Cutler are parents of baby boy No. 2

Kristin Cavallari and Jay Cutler welcomed a new baby son on Wednesday, leaving Mommy outnumbered by the guys three to one.

“Welcome Jaxon Wyatt Cutler,” “The Fabulist” co-host announced on Instagram, giving the baby’s weight at 7 pounds, 11 ounces, and including a picture of tiny sheepskin slippers, Mom’s hospital ID bracelet and a little blue-and-white striped knit hat.

That makes 21-month-old Camden Jack Cutler, who arrived in August 2012, a big brother -- something his parents were excited about from the time they announced they had a second child on the way.

Cam, however, perhaps wasn’t as thrilled about his looming big-bro status.

“We try to tell him there’s a baby inside Mommy’s belly,” Cavallari, 27, told People back in March. “He doesn’t really understand that. We’ll be like, ‘Camden, do you want to be a big brother?’ and he’ll shake his head no.”

According to the magazine, Jaxon was born in Chicago, where Papa Cutler, 31, spends some time quarterbacking the Chicago Bears -- at least for the next seven years.

(By the way, does anyone remember the big Camden kerfuffle of 2012, when Nick and Vanessa Lachey used the same name when their tot arrived two months after the Cutlers’ first child, and then “The Hills” alum tweeted that thing? Nah? OK, nevermind.)

Cutler and Cavallari got married Nashville last June after an on-and-off engagement. They’d started dating in fall 2010.
