Kristin Cavallari has another man in her life.

People reported that the former "Hills" star and her husband NFL quarterback Jay Cutler welcomed their second son named Jaxon Wyatt, on Wednesday. The couple's bundle of joy weighed in at seven pounds, 11 ounces.

Cavallari made the announcement on her social media page, posting a picture of a blue and white striped knitted hat and a pair of miniature moccasin boots, which were wrapped around her hospital ID wristband.

The little one joins big brother Camden, 19 months. The couple, who wed in June 2013 in a Nashville, Tenn., ceremony, announced that they were expecting in October. She unveiled the baby's gender in February via Instagram with a picture of a mustache that read: "It's a BOY."

"I'm lucky," Cavallari told E! News. "Both pregnancies have been really easy for me, I've just been really tired. It's just one of those things where I could literally sleep all day everyday but I'm snapping out of it a little bit now that I'm in the second trimester."

In March, Cavallari made headlines after admitting to FOX Business' "The Independents" that she and Cutler did not vaccine Camden and were not planning on vaccinating their second child either.

"We didn't vaccinate. I read too many books about autism and the studies," Cavallari said. "There's a pediatric group called Homestead, or Home First ...They've never vaccinated any of their children and they haven't had one case of autism. And now one in 88 boys is autistic, which is a really scary statistic."

Cavallari defended her decision during her appearance on Bravo's "Watch What Happens Live" with Andy Cohen.

"There are very scary statistics out there regarding what is in vaccines and what they cause - asthma, allergies, ear infections, all kinds of things. And we feel like we're making the best decision for our kids," she said. "Here's the thing: At the end of the day, I'm just a mom. I'm trying to make the best decision for my kid."
