Kristin Cavallari and husband Jay Culter are about to celebrate their son’s first birthday, an occasion that has the reality star talking about expanding her family.

"We are both ready for baby No. 2," Cavallari said to E! News . "I don't have any announcement today, that's for sure, but we're gettin' there."

Culter, quarterback for the Chicago Bears, and Cavallari married in Nashville, Tennessee on June 7, after welcoming baby Camden the August before. The Hills alum said that she and the athlete have adjusted well to married life, and are enjoying raising their active son.

“Once you live together and have a baby together, not a whole lot changes,” she said. “But it's been great and we're really enjoying it. I have an additional ring on my finger, yes."

As for traveling back and forth from Los Angeles, where Cavallari works, and Chicago, where Culter plays, the 26-year-old says she is lucky that Camden is “an awesome flyer,” despite walking “all over the place,” when he is at their home in California.

“There is no such thing as sitting still anymore,” Cavallari said of her life as a mother.

The Daily Mail reports that Cavallari and son traveled to Los Angeles where the actress filmed for FX’s The League .
