Sarah Palin's 18-year-old daughter Bristol has given birth to a healthy baby boy, People Magazine reports.
Tripp Easton Mitchell Johnston was born in Palmer, Alaska, and weighed in at 7 lb., 4 oz.
"We think it's wonderful," Colleen Jones, the sister of Bristol's grandmother Sally Heath, told People. "The baby is fine and Bristol is doing well. Everyone is excited."
Bristol Palin's pregnancy caused a stir when it became public soon after her mother was tapped to be the Republican vice presidential nominee.
The father of the baby, former Wasilla High School hockey standout Levi Johnston, had announced plans to marry Bristol in 2009.
