Kristin Cavallari and Jay Cutler welcomed their second son into the world on Wednesday, Jaxon Wyatt Cutler.

The reality star made the announcement on Instagram Wednesday with a picture that showed an infant’s hat, booties and a hospital bracelet.

“Welcome to the world, Jaxon Wyatt Cutler 7 lbs. 11 oz. 5/7/14” she wrote with the photo.

Cavallari, 27, and her husband, 31, already have a son, 21-month-old Camden Jack.

The former Hills cast member recently revealed in an interview that Cutler, a quarterback for the Chicago Bears, is a “hands-on” dad.

“He goofs around with Cam and he gets on the floor and plays with him,” she said in an interview. “It’s really cute to see.”

Cavallari also spoke about how pregnancy is much different the second time around.

“[There are] more aches and pains,” she stated. “With the first one you can sleep all day, but now I’m running after Camden.”

The Dancing With the Stars alum and Cutler began dating a few years ago. Reports circulated that they broke up in July of 2011 after getting engaged that April. Despite Cavallari’s own rep even coming out and giving a statement of the break up, Cutler denied the whole thing.

The pair got back together in September of 2011 and re-engaged that November. They then announced they were expecting their first child in January of 2012. Camden came into the world that August.

The couple announced this past October they were expecting again, and in February found out they were having another boy.
