Congratulations are in order for Kristin Cavallari and Jay Cutler. The happily married couple welcomed their first daughter, Saylor James Cutler, to the world on Monday afternoon.

Mom wasted no time sharing the wonderful news with her fans, taking to Instagram to post a snap of a sweet pink and white onesie, coordinating bow, and the tiniest footprints on Saylor's birth certificate—all just hours after delivering baby girl! "Saylor James Cutler was born today at 132pm!!" an excited Cavallari captioned.

Upon closer read, fans can see that little Saylor made her arrival weighing a healthy 7 pounds, 6 ounces at 19 1/4-inches long.

The duo's already proud parents of two boys, Camden Jack, 3, and Jaxon Wyatt, 1. Once the happy family found out that they were expecting a little girl, Cavallari shared on Instagram her sons' excitement to finally have a sister. On top of her never-ending mom duties, Cavallari has kept busy with her shoe line, Kristin Cavallari by Chinese Laundry, plus, the recent release of her book Balancing in Heels. Even her hubby has been putting in long hours as the quarterback for the Chicago Bears. Hopefully, the busy couple will find time to share more adorable photos of their expanding family.
