Sailor is officially a trend! Bristol Palin revealed the name she's chosen for her daughter — and it's all because of Kristin Cavallari! The pregnant star joked that her baby-to-be will be called Sailor, which is what Cavallari chose for her little one.

"When you find out @kristincavallari named her baby the exact name you are naming yours. What a weird coincidence," Palin, 25, wrote via Instagram on Monday, Nov. 23. "Congrats on your new bundle, and I do love her name.. Still naming my baby girl Sailor!" (Liv Tyler's 9-month-old son is also named Sailor.)

In the pic, Palin posted a monogrammed blanket and Christmas stocking that she had created ahead of her daughter's arrival. (Palin and Cavallari were both previously teamed with Mark Ballas on Dancing With the Stars.)

Just hours earlier, Cavallari, 28, announced that she and her husband, Jay Cutler, welcomed their third child together, a girl they named Saylor James. The couple are already parents to sons Camden, 2, and Jaxon, 18 months.

Palin, meanwhile, revealed in June that she's expecting her second child, but kept mum on the father's identity.

Sarah Palin's daughter ended her engagement to Dakota Meyer in May. She is also mom to 6-year-old son, Tripp, whom she had with ex-fiance, Levi Johnston.
