Bristol Palin is officially a mother of two!
E! News can confirm Sarah Palin's daughter has welcomed her second child, a baby girl named Sailor.
"My sweet Sailor Grace was born yesterday, our family couldn't be more complete," Bristol wrote on Instagram Thursday afternoon. "My heart just doubled."
Baby Sailor—who may just be confused with Kristin Cavallari and Jay Cutler's newborn baby girl Saylor—joins big brother Tripp and grandma Sarah who was more than excited at having another grandbaby in the family.
"I can't wait for about 45 more days, and I'm gonna have a little baby granddaughter," the former Vice Presidential candidate told CBS News back in November. "And I'm happy about it."
