Kristin Cavallari has welcomed her first baby girl with her husband Jay Cutler, a sibling for the two sons they already have together. The former reality star has also revealed the infant’s unusual name via Instagram.

The couple’s daughter, named Saylor James Cutler, was born on Monday (November 23rd) weighing 7 pounds and 6 ounces, and is a sister for their two boys Camden, 3, and Jaxon, 1. The new mom announced the arrival by posting a picture of a baby-sized pink dress.

28 year old Cavallari and her husband, who plays quarterback for the Chicago Bears, were married in Nashville in June 2013 and have wasted no time in starting their family, with three kids arriving in a little over 3 years.

Back in September, Cavallari revealed the unusual origin of her imminent arrival’s name. “We picked out this baby girl’s name when I was pregnant with our first,” she said. “I met a woman and her dog, and I loved her dog’s name. Funny enough, it was the name she had picked out if she had a girl, but she had boys, so she used it for her dog instead.”

At around the same time, the former star of MTV’s ‘The Hills’ told Us Weekly about how her pregnancy was progressing. “I'm feeling great! I'm lucky because all three pregnancies have been relatively easy and they've all been the same,” she said at an event in New York. “The only thing is with the girl I feel like I'm carrying a little bit higher, which is kind of interesting. And they do say you carry differently with a girl. So maybe that is true.”
