TV personality Kristin Cavallari, 27, and her NFL quarterback husband Jay Cutler welcomed a new addition to the family on Wednesday.

Cavallari made the announcement about her son's birth via Instagram and Twitter.

She wrote, "Welcome Jaxon Wyatt Cutler 7 lbs 11oz 5/7/14." Cavallari also included a link to a photo showing off her hospital bracelet wrapped around baby Jaxon's booties and blue and white striped hat.

This isn't the first child for the celebrity couple. Cavallari and Cutler have another baby boy named Camden Jack who is only 21 months old.

It's safe to say Kristin wastes no time when it comes to her family.

"The second time around, you know exactly what to expect and we're just ready," Cavallari told People Magazine while she was still pregnant.

"This one, I'm like, ‘Let's get him out here, I want to see him, I just want to hold him and see what he looks like.' I'm just really excited more than anything."

Fortunately for Kristin, she's always had very smooth pregnancies.

"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," she told E! News last year.

Cavallari announced her pregnancy with her second son back in October. She later disclosed the sex of the baby in February.

Though Cavallari is now the mother of two boys, she doesn't seem to be slowing down when it comes to her career. The former reality-TV star currently has both a shoe line called Chinese Laundry and a jewelry line called Glamboutique.

Her fashion savvy does not stop there though.

Cavallari just recently wrapped up the first season of the E! show "The Fabulist" where she and a panel of fashion critics dish on the latest trends in fashion from week to week.
