Kristin Cavallari and husband Jay Cutler welcomed their new baby girl, Saylor James, on Monday, but did they steal the idea for her name from Bristol Palin?

The 25-year-old reality star posted an Instagram pic on Monday of items she has already had embroidered with her unborn baby girl’s name, with the caption, “when you find out @kristincavallari named her baby the exact name you are naming yours ??.”

“What a weird coincidence,” Palin continued, adding that she’s not planning on changing the name. “Congrats on your new bundle, and I do love her name.. Still naming my baby girl Sailor! ??❤️.”

The name are spelled differently: Cavallari and Cutler’s baby girl’s name is spelled with a “y,” while Palin’s daughter will be Sailor with an “i,” like Christie Brinkley’s daughter, Sailor Brinkley Cook, who beat both reality stars to the punch by 17 years.

For her part, Cavallari told ET in October that her idea for the name was inspired by someone else, just not Palin.

“I did hear our daughter’s name at a baby store, the owner had named her dog this and she said at the time, ‘I wanted to name my little girl this name but I never had a little girl,’” she told ET while promoting the Chinese Laundry Fall Fashion Campaign. “And I remember thinking ‘God I love that name,’ and here we are three and a half years later.”

Palin announced that she was expecting a baby girl in October. She is already mother to one son, 6-year-old Tripp, with ex-fiance Levi Johnston.
