Bristol Palin is now a mother of 2.
Sarah Palin's daughter gave birth Wednesday to Sailor Grace. Sailor joins Tripp as part of Bristol's brood.
She hasn't revealed the identity of the daddy, but she announced she was pregnant just a few weeks after she called it quits with fiance Dakota Meyer.
Bristol has fought Tripp's baby daddy Levi Johnston from time to time over custody and child support. Hope this one's smoother sailing.
